Cher Docteur Herzberg:
Le prix Nobel qui vient de vous être
attribué est un honneur qui rejaillit sur
l'ensemble des physiciens canadiens et tout
particulièrement sur l'Association Canadienne
des Physiciens.
C'est donc un honneur pour
moi de me faire le porte-parole de l'Association
Canadienne des Physiciens en vous offrant nos
plus sincères félicitations.
En 1970, à l'occasion de son 25 e anniversaire, l'Association Canadienne des Physiciens
avait reconnu de façon officielle l'importance
de vos travaux de recherche en décidant de
décerner annuellement la médaille Herzberg à
un jeune physicien avant accompli des travaux
exceptionnels. L'honneur dont vous êtes présentement l'objet contribuera, j'en suis
persuadé, à rehausser l'importance de cette
récompense. Nous vous en sommes donc
reconnaissants.
Dans le contexte canadien actuel où l'on
tente d'établir une politique des sciences,
l'attribution du prix Nobel pour la chimie à
un physicien canadien est un événement qui
devrait permettre de mettre en valeur l'importance des recherches fondamentales dans la vie
d'une nation et de souligner la qualité des
recherches fondamentales effectuées au Canada
à l'échelle internationale. Je suis convaincu
que cet événement peut aider le gouvernement à
prendre conscience de la part importante que la
recherche fondamentale doit prendre dans
l'ensemble des activités scientifiques.
Nous sommes fiers de compter maintenant dans
nos rangs la présence d'un prix Nobel. Vous
contribuerez ainsi à rehausser le prestige de
la physique au Canada et, pour cela, je désire
vous exprimer encore une fois nos plus sincères
félicitations et remerciements.
Je vous prier d'agréer, cher Docteur
Herzberg, l'expression de ma plus profonde
admiration.

Dear Sir:
I wish to comment on certain aspects of the
Laurence Committee report on "Purpose and Choice
in the Support of University Research in Physics".
First, I wish to express support for the proposals in Part II that Small Grants be administered by panels in the subfields of Physics (sec.
3), and that objective Merit Rating procedures
be introduced (sec. 5). These measures should
lead to improved granting decisions.
Second, I should like to advance a proposal
regarding the refereeing of small grant applications (Part II, sec. 6.9). Refereeing is a
notoriously difficult problem, and the report's
proposal, that two members of the subfield panel
serve as referees for a given application, is
open to the criticism that the referees may
either fail to appreciate an approach which is
different from their own, for a given problem,
or may still not be adequately informed about
the particular problem outlined in the application. If however, in addition, the Physics
Selection Committee were to name a rather large
"Panel of Referees", consisting of individuals
in whom the Committee had full confidence, and
from which an applicant could select one or more
referees to consider his proposal in detail and
to submit a report on it to the subfield award
panel, then I believe that applicants could feel
more confident that their proposals were receiving fair and intelligent assessment.
Third, I wish to express disagreement with
the recommendation, implicit and explicit in
various places in the report (e.g., Part II,
sec 9, comment no. 9), that more and larger grants
should be given to "Outstanding, etc." applications, and that fewer and smaller grants should
be given for straight "competent" researchers
and proposals. There is an aspect of research
in universities which NRC has steadfastly refused
to acknowledge as deserving of support, and which
the Laurence Committee has also chosen to ignore
(although it was brought to their attention), and
that is that competent academics, doing valid
though unspectacular research, need to be supported in order that their teaching performance (i.e.,
their impact on the next generation of physicists)
may reflect the enthusiasm and realism engendered
by actual research activity. The situation in
Canadian universities is such that if a physicist
fails to get an NRC grant, he is almost certain
to be frozen out of research, and his teaching
effectiveness will consequently be reduced. The
stock answer, that NRC is not in the education
business, will not serve for the Laurence Committee, whose full title, "Purpose and Choice in
the Support of University Research in Physics",
demands that they consider such questions. There
is, however, no indication in their report that
they did consider this question, for they do not
present any statement of it, nor any reasons for
having rejected its implications.
Related to the above issue is another which
is much less easy to formulate, but which I believe
should be aired in relation to the Laurence Committee report. It is reflected in the sickeningly
uncritical "Appraisal by the Steering Committee",
which in effect commends the Laurence Committee
for sticking to the old NRC policies and procedures. The issue is the fact that the Physics
Selection Committee is self-perpetuating, with
the result that it often appears to be dominated
by senior, outstanding (?) physicists who have
developed successful and often highly expensive,
but relatively inflexible, research programs, and
have subsequently diverted much of their effort
to administrative activity. This committee controls, and essentially directs, the national
La Physique au Canada /
research effort in physics, and it is questionable whether, in its present form, it can be
expected to properly assess current trends, and
to represent the physics community which it
effectively governs. Personally, I do not accept
the opinion that benevolent dictatorship by an
enlightened élite is preferable to a democratic
system, particularly in the case of Canadian
physics, where the élite are so little better,
as judged by world standards, than are the
"commoners". Thus, I suggest that a Physics
Selection Committee consisting of elected
representatives of the physics community,
including students, would be much more effective
than one constituted according to the old procedures .
If some of the above remarks are inflammatory,
I hope that offended individuals will discount
that aspect, and will give serious consideration
to what are intended to be constructive proposals.
Yours truly,
John M. Vail,
University of Manitoba
An Open Letter to Erich Vogt, Past President
of the CAP:
Dear Erich:
I read with interest your address to the CAP
Annual Congress in the September issue of Physics
in Canada and was suitably impressed. You are
right; the goal of having only truly creative
Ph.D.'s in research careers is indeed a noble
one and one which could be of considerable benefit to Canada as a whole. There are, however, a
few further suggestions I would like to make
which might help to bring about this happy state.
I would suggest that you put your money where
your mouth is, and that you resign from your
privileged, tenured position and that you persuade your fellow tenured colleagues to similarly
resign in order that they could compete with all
the presently unemployed younger physicists for
the available positions, thereby ensuring that
only the very best people available across North
America and the World would end up in research
positions.
With reference to the current mess created
by the established physics community in which
perhaps 80% of young physicists lack permanent
employment and your historical references, the
significance of which escaped me, I would suggest
that history is full of leaders who have had
disastrous policies. What is perhaps more unusual is that seldom have such policy makers
been so comfortably isolated from the effects of
their own policies.

Dear Sir:
We are five members of the Physics Department,
Memorial University of Newfoundland, who wish,as
private citizens, to add our voices to the mounting protest against the 5-megaton blast planned
3
for Amchitka Island by the U.S. Atomic Energy
Commission. As geophysicists we find special
relevance in the possibility that the bomb might
initiate a major earthquake, to be followed perhaps by a destructive tidal wave of the kind that
did so much damage along the Canadian and U.S.
Pacific coasts after the 1964 Alaskan earthquake.
Our total opposition to this test, however, is
based on the view that it is utterly indefensible
on whatever grounds one cares to examine:
environmental, political, military or moral.
The AEC's dismissal of the earthquake risk
as "highly unlikely", notwithstanding the warnings of seismologists, only stresses the fact
that the body carrying out the test cannot predict, let aloae control, its possible consequences.
This applies also to the chance of radioactive
leakage, with its possibly disastrous effect on
fish populations and wildlife in the North
Pacific. The AEC's record at the Nevada test
site, where more than a quarter of the underground tests have leaked radioactive material,
shows that the risk is a real one. Exploding
the bomb under these circumstances would amount
to irresponsible tampering with the environment.
We believe strongly that the unleashing of
such powerful nuclear blasts can only lead to
escalation of a self-defeating arms race and an
increase in international tensions. Above all,
we protest the Amchitka test because we are
opposed to the construction and testing of all
nuclear weapons. We welcome the stand taken by
the Canadian government on this issue, but would
urge that it base further protests on broader
considerations than purely environmental ones.
Respectfully yours,

Six Radioactivities
by R. E. Bell
Mr. Chairman, Ladies and Gentlemen:
I am very pleased to have been invited to
give a talk in this general interest session on
a topic suitable for the Rutherford Anniversary
year. I should like to dedicate this talk to
the memory of my old teacher, co-worker and
friend, Lloyd Elliott, who died so suddenly
last November 29, a day that just happens to be
my birthday. I think that Lloyd had a little
bit of Rutherford in him, which is as high a
compliment as you can pay an experimental physicist.

Session of the Annual Meeting of the Canadian
Association of Physicists, Ottawa, June 25,

/ Physics in Canada
Rutherford's supreme personal work was the
study of radioactivity at McGill between 1898
and 1907, and it resulted in the largest bulk
of Rutherford's own published papers. The study
of radioactivity has remained an important subject in nuclear physics, and I want to talk
today about the various kinds of radioactivity
and their importance for physics. One of the
ways of enumerating the different kinds of radioactivity produces the answer six, and so I have
entitled my talk today, "Six Radioactivities".
I will be bound to speak at times historically,
but of course I will not confine my point of
view to that of the early workers. All of us
enjoy great advantages of viewpoint over the
people who investigated these phenomena originallyWhat is radioactivity? The definition has
changed over the years, but I will define it as
the emission of radiation or particles on a time
scale that is accessible to measurement by man.
This definition skips over the question,
"emission from what?". Originally one would
have said emission from samples of certain substances; later on, the emission would have been
said to be from atoms, still later nuclei, and
finally from some so-called elementary particles
as well. Very large changes have also taken
place in what time scales are accessible to
measurement by man, but for the purpose of this
talk I restrict the meaning to measurement by
more or less direct and straightforward means.
This itself, of course, has changed very greatly
over the years.
The natural time scale for nuclear process
is somewhere in the neighbourhood of 10 - 2 2 or
10 - 2 3 seconds. This is easily seen if we assume
that nuclei are made of protons and neutrons
held in a common potential well of depth a few
tens of MeV, and having kinetic energies of a
few MeV less than the depth of the well. The
protons and neutrons will then have velocities
of agitation in the nucleus of something like
10 10 centimeters per second. The time required
for one of these particles to be emitted from
the nucleus, if suddenly it became completely
free to leave, would be something like the
radius of a nucleus, 10~*2 to 10 - * 3 centimeters,
divided by the velocity of 101® centimeters per
second, or 1 0 - 2 2 to 1 0 - 2 3 seconds. Times of
this order can be deduced in nuclear and particle
physics, but are too short to be directly measured. Thus we see that what we have defined as
radioactivity is in fact very unusual nuclear
behaviour. Nearly the most important question
about any given type of radioactivity is, why
is this event taking place so slowly?
With this introduction, I will start on my
list of six radioactivities, trying to list some
of the contributions that the study of each of
them has made to physics. My classification of
the radioactivities, which is not the only one
possible, is based on what radiation or particle
is emitted by the nucleus.
The first radioactivity is alpha radioactivity, Rutherford's special favourite.
Becquerel had discovered radioactivity earlier,
and the Curies had done their pioneering work
in what we would now call radio-chemistry, but
it was Rutherford who first noticed that the
radiations from uranium and related radioactive
preparations were complex in nature. Two components were very obvious. Writing in 1899, he
called the more absorbable radiation the alpha
radiation, and the other component the beta
radiation. This observation does not really
identify two different forms of radioactivity,
but in the next few years Rutherford and Soddy
found that alpha and beta radiations were given
out in different amounts by different radioactive substances, and they developed the radioactive displacement laws that confirmed that
alpha and beta radiation came from two different
kinds of radioactivity.
Around 1903, Rutherford became convinced that
the alpha radiation consisted of high-speed
helium ions. The actual proof, which was
spectroscopic, did not come until 1909, but
Rutherford was never in doubt about the matter.
It is hard now for us to realize that there was
no sensible picture of the structure of an atom
at that time, and that the idea that one atom
could emit another, with energies a million times
chemical energies, exposed Rutherford to a good
deal of scepticism, sometimes even ridicule.
The first great contribution of alpha radioactivity to physics was the alpha scattering
experiment that led Rutherford to the nuclear
hypothesis in Manchester in 1911. Alpha particles bombarding a thin foil of some suitable
substance usually penetrated the foil, but
occasionally bounced back in the general direction from which they came. It was Rutherford's
genius to be immediately surprised by this fact,
for as he said, it was as if you were firing
sixteen-inch shells at pieces of paper, and
every once in a while one of the shells bounced
back. Rutherford realized that the only way
this could happen would be to have the mass of
each atom that made up the foil concentrated in
a small volume, so as to provide a concentrated,
massive target for those alpha particles that
happened to come near; this also explained the
rarity of the events. In order to provide an
interaction between the bombarding alpha and
the target nucleus, it is also necessary to
assume that the electric charge is concentrated
on the nucleus as well. The rest is history.
The following year, Bohr spent a year at Manchester, and returned to Copenhagen to write his
historic paper on the nuclear model of the
hydrogen atom in 1913.
A second great contribution of alpha radioactivity lies in the realm of nuclear techniques.
Not only did the alpha radioactivity provide the
first beam of particles for nuclear scattering
experiments, but it also provided the first
objects for display in the Wilson cloud chamber,
the grandfather of all the devices for visualizing particle tracks, as well as the first particles used in the development of what became the
Geiger counter, the ancestor of all our devices
for detecting individual nuclear particles.
In 1919, the alpha particles from radioactive
sources provided for Rutherford the particle beam
that produced the first artificial nuclear transmutation.
Finally, alpha radioactivity posed the problem that led to the whole idea of quantum-mechanical barrier penetration. The problem was, if
an alpha particle was inside the uranium nucleus,
and if on the average it stayed there for lO 4 0
times as long as it would have taken to come out,
if it had been entirely free to come out, then
why should it come out at all? Why also should
raising the energy from the 4 MeV of uranium
alphas to the 8 MeV of the alphas of a neighbouring radioactivity shorten the lifetime by a
La Physique au Canada /
factor of 10 2 3 ? The answer turned up as a new
theoretical phenomenon.

Figure 1.
Figure 1 shows a diagram of the potential
energy between au alpha particle and the rest
of the nucleus as a function of the distance
between the two bodies. At relatively large
distances apart, the interaction between the
two bodies is that of the Coulomb interaction
between them, an electrostatic repulsion increasing as the distance grows smaller, so that
the potential is increasing and positive as the
particles approach each other. As the particles
start to coalesce, however, the strong nuclear
attraction which binds them together takes over,
and the potential well of which I spoke earlier
shows up. If the alpha particle is bound inside
the well, with an energy a few MeV positive (as
we know it must be because it carries that energy
outward), then classically the alpha particle
cannot escape from the nucleus. Experimentally
we know that it does come out eventually, and
therefore there must be some small probability
for the alpha particle to escape, though escaping
is classically impossible. Gamow and Gurney and
Condon showed in 1928 that quantum mechanics
allowed this to happen. Their treatment explained not only why alpha emission is so slow, but
also why it varies so rapidly with the energy of
the emitted alpha particle.
What the alpha particle does while it is
tunnelling the barrier is something that has
bothered generations of students, and usually
they simply learn not to think about it. A few
years ago Bernard Cohen suggested that we should
invoke the uncertainty principle to say that over
a short time the energy of the alpha particle
can fluctuate sufficiently so that it has some
chance of going over the barrier in an honest
manner; he showed that this assumption led
plausibly to the usual WKB formula for the
barrier penetration. I like this way of talking
about the barrier penetration; in fact, not
"penetration", but "surmounting" would be a more
appropriate term on Cohen's picture. I have not
noticed any reference to Cohen's contribution in
physics textbooks.
My second radioactivity is beta radioactivity.
Beta radioactivity is the emission of electrons,
either plus or minus, or the capture of electrons
by the nucleus. Historically, of course, beta
radioactivity meant the emission of negative
electrons. It was concluded very early that the
5
beta electrons were substantially similar to
electrons of non-nuclear origin, but as we shall
see, there is one respect in which they differ,
and physicists were misled about it for about a
quarter of a century.
I said earlier that nuclei were made of
neutrons and protons, and there are very compelling reasons why we should not consider that the
nucleus contains any electrons. We have here
the beginning of the reason why beta radioactivity is so slow compared with characteristic
nuclear times; the nucleus is called upon to
emit something that isn't there. This is not so
strange; after all, a light bulb does not contain light, in the usual sense, but nevertheless
it emits light copiously when suitably stimulated.
It was many years before the true nature of
the energy spectrum of the beta rays was established. When it was, it turned out to be a
continuum roughly as shown in Figure 2. Here we
have plotted the number of beta rays versus
their energy, and we see that the spectrum is a
SETA znetiey
Figure 2.
continuum whose extrapolated end point corresponds to the true energy available in the
nuclear disintegration. Calorimetric measurements of the average energy of a beta disintegration indeed showed that some energy was
missing. In addition, some of the same arguments
that show that there are no electrons in the
nucleus show also that an electron cannot be
produced alone. These facts caused Pauli to
speculate in the early 1930's that there must
be some undetected energetic neutral particle
emitted at the same time as the electron. Fermi
subsequently named this particle the neutrino,
and its existence was treated with scepticism
by many scientists for a very long time. The
neutrino has since been detected as an independent particle at a distance from its origin, and
there is a family of neutrinos whose members
correspond to the processes that produce them.
To know this much about particles that have
neither charge nor mass is a great achievement,
and is a legacy to science from beta radioactivity.
In 1934, Fermi published a paper that
probably holds the record for modest titling
of a paper that was to become an acknowledged
classic; the title was "A Tentative Theory of
Beta Decay". In this paper, Fermi assumed the
neutrino hypothesis, and postulated the creation
of the electron and neutrino (actually antineutrino) in a way analogous to the creation of
6
/ Physics in Canada
a photon by the electromagnetic field.
He
postulated a new interaction, which we now call
the weak interaction, which has taken its place
as one of the four well-established fundamental
interactions of physics.namely the gravitational
interaction, the electromagnetic interaction,
the strong nuclear interaction, and the weak
interaction.
As if beta decay had not contributed enough
to physics, in 1956 and 1957 a sensational
development took place. There had been a mystery
about the modes of decay of what were then known
as the tau and theta mesons via the weak interaction. In 1956, Lee and Yang realized that the
results would make sense if one could assume
that the hitherto sacred law of the conservation
of parity simply did not hold in weak decays.
They pointed out that no previous experiment
with beta emitters had ever tested the point,
and they suggested a number of experimental
tests. What they pointed out was not exactly
right; there had been at least one previous test,
made by Cox and others around 1930. The test
involved double scattering of beta electrons
from radioactive sources, and it showed an
asymmetry between right-left scattering and
right-right or left-left scattering. This
result, if believed, would show that beta
electrons were longitudinally polarized and
that the law of conservation of parity, that is,
reflection symmetry, did not hold for beta decay.
The result was not believed because it contradicted the law of the conservation of parity!
This law continued illegally in force for just
over a quarter of a century.
In 1957, in response to the suggestion of
Lee and Yang, a team of physicists headed by
C. S. Wu performed an experiment in which
cobalt-60 nuclei were polarized in a low temperature apparatus in a magnetic field, and
observations were made of the abundance of beta
rays emitted into the two hemispheres corresponding to the north and south poles of the polarized
cobalt-60 atoms.

Figure 3 shows how the abundance of the two
components of the beta rays behaved as the polarized cobalt-60 was allowed slowly to warm up
and lose its polarization. For the first few
minutes there is a definite asymmetry between
the two hemispheres which disappears at the
same time as other indications show the sample
has lost its polarization. This experiment,
which is another classic, definitely proves
that the law of conservation of parity does not
hold in beta decay.
Since that time there has been a great
extension, amounting almost to a revolution, in
both the theory and experiment concerned with
all weak decays, including beta decay. There
has been and continues to be a critical examination of every sort of supposed conservation law,
or what is the same thing, of every supposed
symmetry property in the world of physics. This
new perspective which has permeated physics for
the last fifteen years is another of the debts
that we owe to beta radioactivity.
The remaining four of my six radioactivities
will be covered a little more quickly. The
third one is gamma radioactivity, often called
nuclear isomerism. All the early workers, from
Rutherford onward, realized that gamma rays,
that is, high-energy electromagnetic radiation,
accompanied both alpha and beta radioactivity
in varying amounts. This electromagnetic radiation is emitted from nuclei that are left in
excited states as a result of the violent rearrangement of an alpha or beta decay. The
electromagnetic interaction is slightly weak,
but the lifetime of a typical excited state for
gamma radiation is perhaps 10" 13 seconds, which
for our purpose can be taken as very short. In
1936, Von Weiszacker suggested that if there
were a nuclear excited state whose angular
momentum was very different from that of any
state below it, the gamma ray emission process
would have to correspond to a high multipolarity,
and the lifetime of the excited state would be
abnormally long.
In 1938, Feather and Bretscher recognized
two separate radioactive lifetimes in one
nuclear species, so that one of the lifetimes
must refer to an excited state. The radioactivity corresponding to this excited state Is
called a nuclear isomer, but I would have preferred to call it a case of gamma radioactivity.
The finding by Feather and Bretscher was succeeded by a number of others, and after the war
the material on this subject accumulated rapidly.
A detailed theory of gamma decay rests on a
securely understood interaction, the electromagnetic interaction, but requires a detailed
model of the nuclear motion; a sketchy theory,
however, can be made on quite elementary grounds.
For some strange reason, this elementary theory
was not done properly, and a number of experimental results were wrongly interpreted, until
in 1951, Goldhaber and Sunyar produced their
famous paper, "Classification of Nuclear Isomers"
At the same time, Weisskopf and Moszkowski were
producing a correct sketchy theory of gamma ray
transition probabilities for the various gamma
multipolarities. Some of the results of the
isomer classification yield extremely consistent
results, in spite of the roughness of the theory.
Correctly analyzed results on nuclear isomers
have been of the utmost value in identifying
the spins and parities of nuclear energy levels
in nuclear spectroscopy, and in checking the
validity of different nuclear models. The
analysis of nuclear isomers links up closely
with the famous shell model of the nucleus, in
which the outer neutrons and protons of the
nucleus are supposed to be in relatively free
orbital motion, as well as with the collective
model of Bohr and Mottelson.
The fourth radioactivity that I wish to discuss, slightly out of chronological order, is
La Physique au Canada / 7
spontaneous fission. The fission of uranium by
neutrons had been going on unrecognized in a
number of laboratories before it was finally
identified by Hahn and Strassman in Germany in
1938. (Not everyone realizes that Otto Hahn
received his initial training in research in
radioactivity from Rutherford at McGill in 1905
and 1906.) The fact that certain heavy fissile
nuclei underwent fission spontaneously was discovered by Petrzhak and Flerov in Russia in 1940.
Spontaneous fission becomes very much more probable as nuclei become heavier, and is one of
the main reasons why nuclei above uranium are
not found in abundance in nature.
Spontaneous fission is a barrier-penetration
phenomenon somewhat similar to alpha decay, but
the shape of the barrier is different. When the
two fission fragments are separate, they are
both positively charged, and hence they repel
each other electrostatically. Before they
separate, we are dealing with a nucleus of varying degrees of deformation.
CCFOK^^TVOA/
—>
Figure 4.
Figure 4 shows the potential energy of such
a nucleus as a function of deformation. It will
be seen that the minimum in the potential curve
occurs at a deformation of about 0.3, meaning
that the long axis of the deformed nucleus is
30% longer than the average diameter of the
nucleus. Clearly such a nucleus will exist
permanently with an average deformation of about
0.3, as all known nuclei heavier than uranium do.
The nucleus may perform shape vibrations about
this stable deformation, so that there will be a
series of vibrational energy levels in the potential well as shown. The hump to the right of
the potential well is the potential barrier
against fission, and in a manner similar to alpha
decay, the nucleus has a chance of penetrating
the barrier and flying apart into two fission
fragments. As we go to heavier nuclei, the equilibrium deformation remains at about the same
point, but the well gets shallower, and spontaneous fission becomes more probable.
An interesting feature of spontaneous fission
has come to light in recent years. It was discovered that certain spontaneously fissioning
nuclei displayed isomerism, meaning that the
same nuclear species displayed two different
lifetimes, a normal spontaneous fission lifetime
and a very much shorter one. No explanation involving gamma radiation would serve, and it took
two or three years to establish that these nuclei
had a second and shallower well in their potential
function, as indicated by the broken line in the
diagram, Fig. 4. This second well is an illustration of the effect of the shell model of the
nucleus, because the neutron and proton numbers
in the nucleus that are "magic" in the sense of
the shell model are functions of the deformation.
It happens for these nuclei that at a deformation of about twice the normal one, one or more
of their nucléon numbers becomes magic, and a
local stability develops at that deformation, as
shown by the secondary well. The secondary well
is shallower than the primary one, and the barriers surrounding it are thinner, and so a
nucleus formed in some nuclear reaction at this
deformation wilj. very quickly undergo spontaneous
fission; the result is the spontaneous-fission
isomer with a short lifetime.
My fifth and sixth radioactivities are
similar enough so that they can be considered
as mirror images of each other; they are delayed
neutron emission and delayed proton emission.
Delayed neutron emission was discovered by
Roberts, Myer and Wang at Chicago in 1939. It
was found that when uranium underwent fission,
about 2.5 neutrons were produced for each
fission event, and that one or two percent of
these neutrons were delayed for periods from
seconds up to hours. The delayed neutrons were
found to decay like a complex radioactivity, but
no one believed that there could be literally
such a thing as neutron radioactivity. The
reason for this is that if the neutron has sufficient energy to leave the nucleus, there is
no barrier to stop it. (For alpha particles,
the potential barrier arises from the combination of the nuclear attraction with the electrostatic repulsion, but for a neutron the electrostatic repulsion is absent.) What then accounted
for the delay in the emission of neutrons? It
soon became apparent that the neutrons were
being emitted from neutron-unstable states
formed by preceding beta decays occurring among
the radioactive fission fragments. The states
that emitted the neutrons have very short lifetimes, as we would expect, but the overall lifetime for the emission of a neutron is governed
by the lifetime of the preceding beta decay.
A more complete name for this form of radioactivity then would be beta-delayed neutron
emission.
Delayed neutrons are of immense value in
the easy control of nuclear reactors. A nuclear
reactor runs at a steady power level when it is
producing on the average exactly as many neutrons
as it consumes. If some of the neutrons it produces are delayed, it means that the response of
the reactor to changes in its own reactivity are
slow, and easy to control. The story is told
when Fermi was building the first reactor, he
was talking to his old colleague, Franco Rasetti.
Rasetti had left physics for paleontology, and
he was strongly religious. Fermi said blasphemously, "Well, if you want to thank God for
something, thank him for the delayed neutron".
There are delayed neutron emitters other than
fission fragments as well.
My sixth radioactivity is delayed proton
emission. Delayed proton events were probably
first observed by Karnaukhov and co-workers in
Dubna in 1962, but the first characterization of
a delayed proton radioactivity was done by R.D.
Barton, now a professor of physics at Carleton
University, in the Foster Radiation Laboratory
at McGill in 1963. The first delayed proton

radioactivity that Barton observed was silicon25,whose proton spectrum is shown in Figure 5.
This spectrum is a more modern one than Barton's
original one, and spectra of still better quality
have been produced since this one was measured

A disintegration scheme of silicon-25 is
shown in Figure 6, where the strongest two peaks
in the preceding figure correspond to emission of
protons from the energy level of 7.91 MeV in
aluminum-25. This state of aluminum-25 is of a
type known as an analog state. If the specifically nuclear force between nucléons is chargeindependent, that is, if it is independent of
whether the nucléons are protons or neutrons or
some of each, then there should exist among the
excited states of aluminum-25 a state whose configuration and nuclear motion are exactly the
same as that of the ground state of silicon-25,
but with one proton turned into a neutron. Such
a state is known as the analog of the ground
state of silicon-25. Beta decay between analog
states should be particularly favoured. It is
a fact that the beta decay from silicon-25 is
more probable to this state than to any other
in aluminum-25, and indeed is one of the most
probable beta decays known. This fact, plus the
roughly anticipated location of the state, gives
us confidence that it is correctly identified as
the analog state. Even though the energy levels
of aluminum-25 had been well explored before,
this state was previously unknown; the reason,
of course, is that in being very similar to the
new delayed proton precursor silicon-25, it was
very different from the states in the previously
known nuclei that had been involved in the
exploration of aluminum-25.
Once the analog states had been located in
the series of delayed proton emitters, some of
them were very much more accurately located by
nuclear reaction studies specifically designed
for the purpose, as a means of exploring the
whole hypothesis of the charge independence of
nuclear forces, or as we would be more likely to
put it nowadays, the conservation of isospin.
Conservation of isospin corresponds to one of
the higher symmetries, the study of which was so
much stimulated by the discovery of the nonconservation of parity in beta decay.
This completes my list of six radioactivities
and their gifts to physics. There have been some
minor omissions. For example, cases of beta
delayed alpha emission are known, and one case
has been found recently of direct barrier-delayed
proton emission, similar to ordinary alpha decay
except that it starts on an excited state. These
phenomena have not yet contributed to physics as
the selected six have. Of course, it is gratifying that so many of the six radioactivities have
had a connection with McGill.
I want to go back now to my starting point,
Rutherford himself. What are the chances that
we are producing now or will produce in the next
while another Rutherford? No doubt you have to
be extraordinarily lucky even to have a chance
to do it. What sometimes depresses me, however,
is the thought that even if we had a chance, we
would not have the wit or the daring to seize it.
Ernest Rutherford was appointed to the Macdonald
Chair in Physics at McGill while he was still a
graduate student, without teaching experience,
at the age of 26. As he said himself at the
time in a letter to his fiancee, "The beard of
manhood is still faint upon my cheeks". He was
attracted to McGill by the prospects for research
because, "the physical laboratory is the best of
its kind in the world", as he wrote to his mother
immediately after his appointment. What are the
chances today of our recognizing a young Rutherford and offering him the same kind of attractive
facilities and the same generous appointment?
I am afraid I do not think they are very good.
Everyone seems to agree that scientific
accomplishment today must come from large teams,
sound management and planning, program budgeting,
and similar dreary features. Probably that is
right, but I cannot help hoping that from time
to time we will have a combination of good luck
and good management that will bring us another
young Rutherford.
1971 NOBEL PRIZE WINNER, DR. GERHARD HERZBERG
The executive of the C.A.P. has struck an
ad hoc committee consisting of H. Welch,
Chairman, B. Stoicheff and D. E. Brodie, to
prepare a March 1972 issue of Physios in Canada,
which will include special features to commemorate Dr. G. Herzberg's winning of the 1971
Nobel Prize in Chemistry.
L'Université Laval assure
maintenant le leadership de
l'Astrophysique au Québec
En moins d'une huitaine d'années de travail
acharné, une équipe du Département de physique
a permis à l'Université Laval d'assurer le
leadership de la recherche en astrophysique au
Québec.
Bien plus, en favorisant la construction
d'un observatoire astronomique sur une montagne
située dans les premiers contreforts des Appalaches à St-Elzéar de Beauce (40 milles de
Québec environ), l'Université Laval devient la
seule institution universitaire à l'est d'Ottawa
à assurer le fonctionnement d'un télescope
professionnel de 40 cm d'ouverture.
Le 2 octobre 1971 l'Université Laval a
procédé à l'inauguration de l'observatoire de
St.-Elzéar. L'inauguration c'est fait au terme
d'un symposium sur les images télescopiques que
le comité d'astrophysique de l'Université Laval
a organisé le 1er et le 2 octobre.
St-Elzéar: le meilleur compromis
A l'échelle provinciale, la région de Beauce
où se trouve le site de l'observatoire astronomique de l'Université Laval, constitue le
meilleur compromis en fonction des trois facteurs essentiels pour une saine utilisation d'un
télescope: (a) la turbulence atmosphérique;
(b) la luminosité du ciel; (c) les conditions
météorologiques.
C'est en considération de ces trois facteurs
essentiels et après étude de d'autres régions
le Comité d'astrophysique de l'Université Laval
fixa son choix sur une montagne (sans nom)
située dans les premiers contreforts des Appalaches dès le mois de février 1968. Tout laisse

croire que ce site pourra être utilisé également
pour des développements futurs déjà envisagés
mais encore à l'état de projet. Ce projet (le
principal) consiste à doter le Québec d'un
observatoire pouvant abriter un instrument de
36 à 48 pouces, en comparison de celui de 16
pouces de l'observatoire actuel.
Le nouvel observatoire envisagé pourrait
nécessiter des investisements de l'ordre d'un
demi-million de dollars ($500,000.) mais ce qui
est intéressant, c'est que ce projet pourrait
être réalisé par l'Université Laval en collaboration avec d'autres universités comme l'Université de Montréal et de Sherbrooke, par exemple
et deviendrait le véritable centre de recherches
en astrophysique au Québec.
Fiche technique de l'édifice
L'édifice est un tour octogonale formée de
dalles de béton précontraint de 34 pieds de
hauteur, 8 pieds de largeur, 4 pouces d'epaisseur et portant chacune deux nervures dorsales
de 18 pouces. Ces dalles, hissées verticalement à l'aide d'une grue, sont soudées à leur
jonction et comportent, aux niveaux appropriés,
des ancrages pour les planchers. Une travée
annulaire en béton armé est coulée au sommet de
la tour pour recevoir la coupole de 16-1/2 pieds
de diamètre.
L'ensemble de l'observatoire compte trois
étages. Un rez-de-chaussée sert d'entrepôt
tandis qu'un premier étage forme le cartier
d'habitation, un deuxième étage comporte un
laboratoire d'électronique ainsi qu'un laboratoire photographique alors que le troisième
étage recouvert du dôme abrite le télescope
lui-même.
Notons en passant que l'édifice est pourvu
des éléments de confort domestique comme l'eau
chaud et froide, l'électricité, le téléphone et
le chauffage électrique. De plus, tout l'ameublement de l'observatoire a été réalisé par
M. Gilles Giroux, du Département de physique.
Au centre de l'édifice se dresse une colonne de
36 pouces de diamètre qui part du sol et se rend
au dernier étage. C'est sur cette colonne
complètement isolée de l'édifice lui-même qu'est
boulonné le télescope de l'observatoire. Cette
colonne essentielle au bon fonctionnement de

Applied Physics at the
Ontario Research
Foundation
by H. Pullan,
Director
A surprisingly large number of people
believe that the Ontario Research Foundation
is some sort of Provincial government laboratory. A much smaller group assumes that we
are a philanthropic organization which does
research at no charge or gives out funds to
deserving individuals. Possibly these misapprehensions arise from our name. In fact
we are an independent non-profit applied research institute which undertakes work under
contract to industrial and government clients.
The Foundation was established in 1928 through
the joint efforts of the Canadian Manufacturer's
Association and the Ontario Government, and
today it provides more direct assistance to
Canadian industry than any other research
institute in the country. Between a quarter
and a third of our total income is supplied as
a grant from the Ontario Government; these
funds are used either to support back-up
research work in areas in which contract work
is already being done, or to enable us to enter
new areas as the need arises.
The Foundation's operations are divided
among seven departments: Physical, Organic, and
Materials Chemistry; Engineering, Metallurgy,
Physics, and Textiles. Although part of the
Physics Department's efforts are taken up in
cooperating with or advising other departments
in physics matters, the bulk of our activities
are concerned with direct contract work and the
in-house research which backs it up. At the
present time there are ten members of the Physics
Department, half of whom are professional physicists .
Our longest-term work is in the field of ion
implantation, with special reference to the doping of semiconductors. The general objective of
this programme is to develop techniques to the
point where they can be of use to various Canadian companies. We started right at the beginning - by designing and building our own ion
accelerator, which became operational about two
years ago. Beams of a few microamperes, at
energies up to 150 keV, are available for over
twenty ion species. The system includes an
electromagnetic mass-separator stage having a
resolving power of 150, which is adequate for
our purposes. More recently we have built a
deflection system which enables the focussed
ion beam to be scanned over a one-inch square
with a uniformity of around one percent.
In parallel with the implantation facility
we have set up a reasonably comprehensive laboratory for preparing and processing semiconductor
materials. In addition to the usual operations
such as cutting, etching and measuring resistivity and dislocation densities, we can grow
single crystals of compound semiconductors such
as zinc telluride, make Hall coefficient measurements down to 2°K, and study photoluminescence
using a 500 milliwatt argon laser and a double
monochromator.
With the implantation system as the basic
tool we have performed, or are performing, work
for six Canadian companies, all of whom are
interested in the development of devices which
benefit from the use of ion implantation in one
or more stages of their manufacture. These
devices include electroluminescent diodes based
on compound semiconductors, position-sensitive
gamma-ray counters, avalanche photodiodes,
energy conversion devices using forward-biased
silicon diodes with beta radiation power input,
and thin-film resistors and thermometers having
improved characteristics due to implantation.
A different area of application, in which
we are now conducting a small feasibility programme, concerns the implantation of krypton-85
to known shallow depths in various objects or
materials. We are interested in whether subsequent monitoring of the implanted radioactivity
can shed useful light on erosion, corrosion, and
the very early stages of mechanical wear. Success
in this work could mean the availability of a
method for monitoring the useful remaining life
of bearings in complex mechanical equipment such
as jet engines, to name just one example.
A small but steady effort on thin-film
physics over the last four years, both with and
without contract support, has touched on areas
ranging from thin films of amorphous tantalum
which become, somewhat surprisingly, superconducting at low temperatures, to thin-film thermocouples, resistance thermometers and strain
gauges. In addition, certain improvements have
been made to our ultra-high vacuum evaporator,
such as an automatic shutter system which is
compatible with UHV requirements.
Another small development programme is concerned with industrial applications of CO2 lasers.
A TEA laser delivering energy pulses of the order
of one joule at 15 p.p.s. has been built together
with a CW unit having about 50 watts output. Some
applications studies are in hand, and a germanium
photon-drag detector system containing an integral
preamplifier has been developed.
Under contract with Atomic Energy of Canada
Limited we have for some time been engaged in
the growth and evaluation of large germanium
crystals for use in gamma-ray spectrometry. By
"large" we mean 5 kg in weight, and 60 or 70 mm
in diameter. As with the ion implantation work,
the first step was to build suitable equipment;
in this case it was a Czochralski crystal-puller
designed along fairly conventional lines except
for the increased dimensions. As one often
finds when scaling up equipment, problems arose
which were not all foreseen. The six-inch diameter of the melt means, for example, that one
is more sensitive to turbulence and vibration
effects than with the normal size of Czochralski
furnace. Large single crystals can now be grown
routinely, although not always under conditions
which give the most desirable density and distribution of dislocations. In common with other
workers in this field, we have found that one of
the most severe problems is the elimination of
the unwanted effects of carrier trapping. These
are probably associated with the presence of unidentified contaminants in amounts which may be
as small as 1 part in 10 1 0 .
Last to be described, but not least in
importance, is our Electron Optical Laboratory.
This is in fact a suite of nine separate rooms,
devoted to operations, specimen preparation,
and equipment maintenance. The emphasis here
is somewhat different from that of the rest of
the Department, in that the objective is to
supply an extremely sophisticated service to a
wide range of clients. As far as I am aware,
the versatility and scope of this laboratory
is unequalled elsewhere in Canada. The key
items of equipment are a microprobe analyser
(AEI SEM2A), a scanning electron microscope
(Cambridge Stereoscan, the new model S4), and
two transmission electron microscopes (JEM 100U
and Siemens la). In the first half of 1971 just
over 100 separate tasks were performed for external clients. This service work is backed up
by a development programme in which both equipment capability and operating techniques are
being continually improved and extended.
The most important part of this Laboratory
is undoubtedly the microprobe, because of its
ability to perform a chemical analysis of
selected small areas of a solid surface. In its
simplest form of operation, one searches manually
through the x-ray spectrum to obtain a qualitative indication of the elements present in the
specimen under examination. This is, in fact,
the limit of sophistication with many of the
microprobes currently in use. We have developed
a rather comprehensive series of computer programmes which allow us to obtain accurate
compositional data despite the complexity of
the necessary corrections for absorption and
fluorescence. With the principal programme we
can analyze for any eight elements (except for
the lightest four), with the sum of the final
weight percentages frequently lying between 96
and 104%. A simpler, and hence cheaper, version
allows the determination of a single element's
concentration when the rest of the composition
is known (how much phosphorus is impregnated
into today's sample of wool?). With our latest
programme, which is coupled with paper-tape
control of the microprobe, a semiquantitative
search for the presence of 50 elements can now
be performed automatically, and in a far shorter
time than was possible under manual operation.
A recent task of considerable complexity was the
determination of the molar composition of several
phases in a series of cement samples. Since
these phases were barely visible at 300X in the
optical microscope, the initial step of positively identifying the samples in the microprobe
called for the development of certain special
techniques.
Service work with the SEM and transmission
microscope tends to be of a more routine nature.
Nevertheless, there is still ample room for
developing improvements in equipment versatility.
As and when time permits, we are examining the
relatively new -field of cathodoluminescence,
since this seems to hold promise for the ready
identification of certain constituents in a
sample which may otherwise prove difficult. An
improved method for the display of stereo images
is also under development.
As the reader will have gathered, we cover
a lot of ground in view of the small size of the
group. Some might say that the ground-cover is
too thin; my reply to that suggestion would be
to point out that since the bulk of our income
comes from a variety of separate industrial
sources, over-specialization can hold more
dangers for our future well-being than its
opposite.

The Err-Um Fumble Bumble Bug.
A confusing virus that attacks the over-confident unprepared lecturer. When attacked by this
bug the lecturer never approaches the topic
direct but gyrates verbally in never decreasing
circumlocutary arguments towards his obscure objectives. His hand tends to wander aimlessly
over the blackboard leaving a semidecipherable
hieroglyphic track of chalk dust constantly
altered by a vacillitory motion of the hand.The
main symptom is an irritating cough which repeatedly interrupts the presentation - "err-hump,
err-hump, err-hump" and occasionally the lecturer
undergoes an acute attack of convoluted statements. The tenure system tends to protect the
individual from the antidote which is a suitable
healthy dose of economic insecurity.

Triumf,1971
by Neil Brearley
Columbia.
, TRIUMF, University
of
British
In about two years time, TRIUMF - the meson
facility currently under construction by a consortium comprising the three public universities
of British Columbia plus the University of
Alberta - will deliver its first external beam.
This article reports on the current status of
the project, and updates the previous report
which appeared in the Winter, 1966, issue of
Physios
in
Canada.
At that time a proposal had been prepared
and an application made to the Atomic Energy
Control Board for funds to build the project.
The application was approved in April, 1968,
and detailed design work started in that year.
In October, 1969, the staff moved into new
office, laboratory and workshop buildings on
the south campus of the University of British
Columbia. Orders for major components began to
be placed in 1970, and in February, 1970, construction commenced on the main building,
designed to house the accelerator and associated
experimental areas.
Briefly, TRIUMF is a meson workshop centred
around a six-sector AVF cyclotron capable of
accelerating H~ ions to a maximum energy of 500
MeV. Extracted proton beams, variable in energy
from 150 to 500 MeV, will be obtained by stripping
two electrons from the H~ ions by passing them
through a thin foil at a radius corresponding to
the desired extraction energy. The protons thus
produced immediately swerve out of the machine,
and hence extraction is essentially 100 percent
efficient. It will be possible to extract four
beams simultaneously, but initially provision is
being made for only two.
The intensity of the extracted beam will be
100 yA at 500 MeV, and 400 pA at 450 MeV. The
limit is set by the beam spill - due primarily
to electric dissociation of the H~ ions in the
outer orbits - that can be tolerated without
causing excessive activation of the cyclotron
components.
The microduty structure of the beam is
determined by the RF phase acceptance, which
will result in a 4 nsec burst every 44 nsec (the
latter figure is set by the 23 MHz RF accelerating field, itself five times the ion rotation
frequency of 4.6 MHz). Provision is being made
to flat-top the RF waveform by adding a proportion of third harmonic component to the fundamental waveform. This will improve the phase
acceptance, giving a microduty structure of an
11 nsec burst every 44 nsec. The energy resolution of 500 MeV will be ±600 keV initially. By
use of energy defining slits it should be
possible to reduce this to ±140 keV at a sacrifice of phase acceptance, and even higher
resolution (±60 keV) should be possible by use
of single-turn extraction.
A full-scale model of the central region of
the cyclotron has been constructed in order to
study the properties of the ions during injection
and the first six or seven orbits. Model studies
would have been necessary in any event - building
a full-size model has not only avoided scaling
problems but has provided a test bed on which
vacuum components, resonators, the ion source
and injection system, and other items could be
evaluated. The Central Region Model, therefore,
constitutes a 60 in. diameter cyclotron producing
particles of 2.5 MeV. A 160 kW RF amplifier has
been obtained and is being used to power this
model. The magnet and associated power supplies
for the model are on site and field measurements
have been completed.
An Ehlers-type H ion source consisting of a
magnetically confined arc and electrostatic extraction electrodes, together with associated
power supplies, has been purchased from Cyclotron
Corporation, Berkeley, California. This unit has
delivered 2.5 mA of H~ ions well within the
emittance of 42 mm rad at 300 keV, the chosen
injection energy. The ion beam transport system
uses electrostatic quadrupoles, and inflector
prototypes have been made using a computercontrolled milling machine. Full operation of
the Central Region Model is scheduled for late
1971.
Cyclotron Construction
The largest - and costliest - individual
component of the machine is the magnet. As mentioned above, the H" ions may be dissociated to
neutral H by the electric force resulting from
their movement through the magnetic field. (There
is also some stripping from collisions with
residual gas atoms in the vacuum tank.) This
sets a limit to the maximum magnetic field
strength that can be used and, in order to determine the stripping parameters with the precision
required for design of the magnet, a direct
measurement of the lifetime of the H~ ion was
made by a team from the University of Alberta,
using the Proton Linear Accelerator at the
Rutherford Laboratory. As a result of this work
the maximum field for the TRIUMF magnet was set
at 5.76 kG.
The design of the magnet involved the use of
a series of 1:20 scale models, and by March 1969
a shape had been established which gave a focused
isochronous beam out to 500 MeV, with a 6 percent
stripping loss. Scaled up, the 500 MeV radius
was 312 in. from the centre of the machine and
the weight of the magnet steel totalled 4,000
tons. The magnet consists of six C-shaped
sectors, the shape dictated by focusing requirements and the necessity to maintain the isochronous condition. Because of the large size
of the magnet, fabrication of the sectors from
plates of low-carbon steel was selected as being
the most practicable and economical method of
construction. The plates are 3, 5 and 10 in.
thick and are being cut to shape and assembled
by Davie Shipbuilding Ltd. of Lauzon, Quebec.
The first sector arrived on site in July of this
year. Figure 1 shows the magnet sectors in process of assembly in the cyclotron vault.
The magnet is excited by two coils, one
above and one below the vacuum tank. Each coil
is made up of 15 water-cooled aluminum extrusions,
each 18.8 in. by 1.16 in. in cross-section,
arranged side-by-side. The coils will require
used and, in order to keep down their size, they
are operated at five times the ion rotation frequency (i.e., at around 23 MHz, making X/4 about
10 ft.). The resonators will be fabricated from
panels comprising a copper conducting layer rollbonded to aluminum. The panels have integral
cooling channels through which water is circulated. The panels are manufactured by the
Vereinigte Deutsch Metallwerke of West Germany,
and the resonators by Ebco Industries of Richmond,
B.C.

about 3 MW of dc power at a current of 27500 A,
regulated to one part in 10 5 . The coils are
being supplied by National Electric Coil Company
of Columbus, Ohio, and the associated power
supplies by Alpha Division of Systron-Donner,
Oakland, California.
In order to achieve the desired focusing and
to maintain the isochronous condition it is
necessary to adjust the magnetic field pattern
to within about one gauss over the whole area.
Initial corrections will be made by adding steel
shim plates to the magnet poles, and final field
profiling will be achieved by means of a number
of separately excited trim and harmonic coils
attached to the lid and base of the vacuum tank.
Fifty-four trim coil pairs will be installed,
together with 12 harmonic coil pairs at different
radii for each of the six magnet sectors.
The gap between the magnet pole-pieces
accommodates the vacuum tank. This is a large
pill-box, measuring 676 in. in diameter and
18.8 in. deep. It will be made of 7/8 in. thick
stainless steel and weigh about 112 tons. Over
200 ports are required in the tank to accommodate cooling lines, cables, probes and the like.
The tank is being fabricated by Ebco Industries
Ltd. of Richmond, B.C., who also built the
vacuum tank for the Central Region Model.
The vacuum system will use conventional
mechanical and diffusion pumps, but will rely
primarily on a cryogenic pumping system using
helium-cooled pipes at 20°K to achieve a
pressure of less than 3 x 10~ 7 Torr. One (of
two) type B-20 cryogenerators has been received
from Philips Gloeilampenfabrieken in the Netherlands .
To permit servicing of components inside
the vacuum tank the whole top assembly - magnet,
tank lid and upper resonators - can be raised
42 in. by means of a jacking system on the
support structure. This support structure is
also used to anchor a system of tie rods
attached to the vacuum tank lid. Similar tie
rods are attached between the tank base and the
machine foundations. These tie rods, together
with a stainless-steel centre post, serve to
prevent the evacuated tank from collapsing under
the 2700-ton atmospheric load.
The large size of the cyclotron precluded
the use of conventional "Dees" as accelerating
electrodes. Instead, X/4 resonant cavities are
About 1.6 MW of RF power will be required to
energize the resonators, the Dee-to-Dee voltage
being 200 kV peak. A power supply for this
purpose is being designed and constructed by
Continental Electronics Corp. of Dallas, Texas,
who also built the RF amplifier for the Central
Region Model. Assembly and test will be done on
site.
Two extraction probes carrying thin carbon
foils (^ 4 mg/cm 2 ) for stripping the H - ions to
protons are being provided. These probes will
have a positioning accuracy of ±.025 in. vertically and ±0.10 deg azimuthally with motion sufficient to provide the required energy variation
from 150 MeV to 500 MeV. As the foils can only
be easily cooled by radiation they will have a
limited life under full beam power conditions.
Consequently, chamber exchange ports are required
on the tank, and the probe mechanism must be
designed for simple remote interchange of the
foil assembly.
Numerous other diagnostic probes of comparable design tolerances are required, some for
use only in early machine physics studies at low
beam currents after which they may be forgotten.
Enough are being provided so that even if some
of the beam sensors inadvertently burn out it
will not be necessary to break the vacuum and
raise the lid merely to repair a probe.
The control system will adopt the CAMAC
standards, and control data will be transmitted
in digital form throughout the facility. Information will be encoded or decoded at either end of
the data transmission link. One of the principal
reasons for selecting CAMAC is that it has a
well-defined addressing means which allows manual
control of the site devices.
The ion source and injection system for the
Central Region Model is being used as a test bed
for the controls engineering approach. Prototype
models of CAMAC digital control modules, digital/
analogue converter modules, multiplex analogue/
digital modules, an optical branch highway and
branch highway drivers have been manufactured in
co-operation with local electronics firms. Three
Supernova computers have been delivered by Datagen of Canada Ltd., and three more are on order.
Buildings
Currently the group at the main site is
housed in the office, laboratory and workshop
buildings occupied in October 1969. The main
building, which will house the accelerator and
experimental areas, is now essentially complete
and the erection of cyclotron components is under
way. The layout of the building at experimental
floor level, 25 ft. below grade, is shown in
Figure 2. Locating the building below grade in
this way permits utilization of the earth around
the building as inexpensive shielding. Practically all other shielding will be in the form of

removable blocks so that it will be possible to
change beam lines without too much difficulty.
The cyclotron itself will be in a concrete vault
with 17 ft. thick concrete walls and 17 ft. of
removable concrete roof beams.
Experimenters' local control rooms will be
at grade level, above the experimental floors
rather than to one side as is the practice at
most laboratories. The experimental hall is
serviced by two 50-ton bridge cranes, each
having two 25-ton hooks. The cranes can be
synchronized to provide a total lifting capacity
of 100 tons.
Experimental Facilities
Initially two proton beams will be extracted
from the machine, though provision is being made
for four beams to be extracted simultaneously.
One beam, limited to 10 liA, will be directed to
a proton area where experiments with the primary
protons will be performed. The second main beam
is directed along a beam tunnel in which two
meson production targets will be located.
The first meson production target, having a
thickness of 4 g cm - 2 carbon equivalent, will be
of beryllium or water. This target will feed a
general purpose pion channel of moderate resolution, designed primarily for pion-nucleon interaction studies. In order to achieve a small,
bright source and to make optimum use of the
p + p •+• IT+ + d reaction, near zero-degree
acceptance of the pion beam will be adopted. The
yield of n + at the channel exit with 100 pA of
500 MeV protons incident on a water target is
expected to be 20 x i o 7 MeV -1 sec -1 .
The second target station will contain
beryllium and copper targets of approximately
20 g cm - 2 carbon equivalent. This will feed a
channe] designed to produce a large flux of
stopping pions with minimum contamination. At
present, measurements at 740 MeV and 600 MeV
indicate that the distribution of pions of
energies below 50 MeV is practically isotropic.
As this situation is expected also to occur at
500 MeV, a channel is being designed which will
view the target at a large backward angle (135
deg). The total possible stopping fluxes have
been estimated to be 6 x 10® n~ sec -1 and
1.8 x 109 n + sec 1 and the muon yields about
one-tenth of these. This target station will
also feed n - mesons of energy 30 - 110 MeV to
a radiobiological and radiotherapy facility.
This facility is a project of the British
Columbia Cancer Treatment and Research Foundation.
The degraded beam will finally be absorbed
in a target of either lead-bismuth or depleted
uranium cooled by light water and surrounded by
a moderator of heavy water and graphite. The
design of the neutron target included facilities
for proton irradiation as well as means for irradiating samples in the neutron flux. A swimming pool, hot cells, and associated radiochemistry laboratories will be provided for
processing irradiated samples. Provision will
also be made for neutron diffraction, neutron
capture x-ray spectroscopy, and neutron scattering
spectroscopy. The thermal neutron flux is expected to be 6 x 10 1 2 neutrons cm - 2 sec -1 for
100 uA of incident 500 MeV protons.
In conclusion, it may be remarked that the
project as a whole is on schedule and, as contracts have been placed for nearly all major
items, it appears that the machine and buildings
will be completed within the original budget.
TRIUMF is scheduled to produce its first beam
towards the end of 1973, initial operation will
be restricted to low intensities (^ 1 uA) in
order to avoid undue activation of machine components. Potential users are submitting
proposals for use of the facility to a recently
established Experiments Evaluation Committee
chaired by J. T. Sample of the University of
Alberta. It is intended that TRIUMF will be
available to all qualified users, regardless of
their affiliation, and proposals are invited
from interested groups.
It is important also to stress that successful completion of this - Canada's largest current
science project - will result from the teamwork
demonstrated by a diversified group of scientists
and engineers. Many of the latter have been
drawn from Canadian manufacturers and consulting
firms, and the experience gained by them will
hopefully have a bearing on Canada's ability to
compete for design work on other advanced projects. All the firms involved have shown an
impressive ability to meet deadlines in the
production of intricate and unusual components,
and have demonstrated a high quality of workmanship. The influence of the project, therefore,
extends beyond its purely scientific interest to
the development of new, science-based, industry
in Canada.

Kingston, Ontario, before April 1, 1972.
We hope to produce the Congress bulletin
this year with a minimum amount of typing in
the bulletin office and therefore with a minimum
amount of delay. Abstracts of papers must,
therefore, be prepared by the authors for direct
photo-reduction to the bulletin size. Except
for photographic reduction, the material will
then appear exactly as the author prepares it.
Abstract rules will be printed in detail in
the March issue of Physios in Canada. Those
who plan well ahead and wish to write an abstract
before the March issue appears, should consult
the identical APS abstract rules.
1972 CONGRES DE A C P: UNE REQUETE POUR DES
RESINES.
Le Congres de 1972 aura lieu à l'université
de l'Alberta, le lundi au jeudi, 26 - 29 juin.
La soumission des mémoires de durée de 10
minutes, sur n'importe quel domain de la physique, sera bien accuellie par l'Association.
Les résumés doivent être reçus avant le 1 e r
avril, 1972, au bureau du "Program Chairman",
Dr. A. T. Stewart, Physics Department, Queen's
University, Kingston, Ontario.
Cette année-ci on éspère que le bulletin du
congres soit produit avec le moindre des mots
que possible et ainsi avec le moindre de délai.
Donc, les résumés des mémoires doivent être
préparés par les auteurs de telle sorte qu'ils
puissent être réduits photographiquement à la
dimension du bulletin. A l'exception de la
photo-reduction le matérial s'apparaîtra
exactement comme l'aurait été préparé par

the Government of Canada may, through
measures within its fields of jurisdiction, have a beneficial influence
on the application and development of
science and technology in Canada,
the coordination of programs and
activities regarding science and technology with other policies and programs
of the Government of Canada, and
the fostering of cooperative relationships with respect to science and technology with the provinces, with public
and private organizations, and with
other nations.
- that the Minister of State for Science
and Technology shall, in relation to the formulation and development of the aforementioned
policies, have such duties as may be assigned
to him by law, and without limiting the generality of the foregoing, shall assist departments
(b)
(c)
(d)
the optimum investment in, and application of, science and technology in
pursuit of national objectives,
the organization of the scientific
establishment in the public service of
Canada,
the allocation of financial, personnel
and other resources to Canadian
endeavours, and
the extent and nature of Canada's
participation in international scientific activities and the coordination
of related domestic activities.
- that the Minister of State for Science and
Technology may
(a)
(b)
initiate and undertake such research,
analysis and policy studies as may be
required to further knowledge and understanding of the impact of science and
technology on society, and
determine and promote the use of methods
for assessing the effectiveness of scientific policies and programs.

PARTICLE PHYSICS IN CANADA: SOME PROGRESS AND
A BIT OF HISTORY.
The conception and birth of the Institute of
Particle Physics has been reported in Physios in
Canada, January 1, 1971 (page 4) and May 1, 1971
(page 54). The Institute has just completed its
first major task, that of submitting a grant
application to NRC for the support of the experimental program In particle physics in Canada.
Responsibility for drawing up this application
was in the hands of Professor Bernard Margolis
of McGill University, Chairman of the IPP Council.
At the first General Meeting of the I.P.P.
at the University of Toronto on April 3, 1971,
a resolution was passed unanimously to the effect
that Dr. Franco Rasetti be invited to be an
"Honorary Charter Member" of the Institute. A
letter has recently been received from Dr.
Rasetti which, after apologizing for not replying earlier because of his absence from Rome
during the Summer, says:
I am pleased to accept the title of
'Honorary Charter Member' of the new
Institute of Particle Physics, especially
as nowadays physics proceeds at such a
rapid pace, that contributions made in
such remote past as 1941 to be entirely
forgotten, and most physicists of the
younger generation do not even know the
names of those who contributed to
particle physics in those days. Therefore, it comes to me as a surprise
mixed with pleasure being remembered
after 30 years.
With best regards,
Yours sincerely,
(signed)
Franco Rasetti."
Following is a short biographical sketch* of
Dr. Rasetti which I read at the I.P.P. Meeting.
Franco Rasetti
Dr. Rasetti was b o m in Castiglion del Lago,
Italy, on August 10, 1901. He received his
Doctorate in Physics from the University of Pisa
in 1923 and has also received an Honorary Ph.D.
from Laval University in 1948, and an Honorary
LL.D. from the University of Glasgow in 1957.
He was instructor in Physics in Florence
during the period 1923-26, and then moved to
the University of Rome where he was Assistant
Professor from 1927 to 1930, Associate Professor
in Spectroscopy from 1931 to 1933, and Professor
from 1934 to 1938. Dr. Rasetti came to Laval
University in 1939 and remained until 1947.
While at Laval he carried out the first experimental investigation in Canada in the area which
can be called particle physics in modern terminology. With the cosmic radiation as a source
and using Geiger counters and vacuum tube circuitry, he made the first direct measurements
of the decay lifetime of the muon. His first
result in 1941 was 1.5 ± 0.3 microseconds, in
quite good agreement with the latest modern
determination. His experiments are recorded
* I am grateful to Laval University and to
Johns Hopkins University for providing much
useful information.
in four publications in the Physical Review in
1941.
I met Dr. Rasetti in Montreal in 1944 at the
home of a mutual friend. He was at that time
keenly interested in the peculiar place of the
muon in the scheme of nature as it was then
understood and its possible connection with the
Yukawa meson. His apparatus was to be a prototype for an apparatus which Bruno Pontecorvo and
I later used to attempt to clarify the nature of
the muon decay. Parts of Rasetti's apparatus
still exist at Laval, as does the name-plate
from his office door which hangs in a collection
commemorating former faculty members and guests.
Had it not been for the war, Prof. Rasetti
would probably have continued his activity in
particle physics, but he found the problem of
doing anything related to nuclear physics outside the secrecy-shrouded government laboratories
so unsatisfactory that he turned instead to a
hobby, paleontology, with increasing enthusiasm.
Within a few years he became internationally
known in that field.
Dr. Rasetti moved to Johns Hopkins in 1947.
He remained there until his retirement in 1967
when he returned to Italy.
During his career, Dr. Rasetti also had
associations with the Rockefeller Foundation at
the California Institute of Technology (1928-29) ,
the Kaiser Wilhelm Institute in Berlin (1931-32),
Columbia University (1936), and the University
of Miami (1958-59). He was Guggenheim Memorial
Foundation Fellow in 1939, Honorary Research
Associate in paleobiology at the Smithsonian
Institute in 1964- , and Consultant to the
National Committee of Nuclear Research, Rome,
in 1959.
His interests have spanned a variety of
subjects which include atomic and molecular
spectroscopy, Raman effect, artificial radioactivity induced by neutrons and properties of
slow neutrons, cosmic rays, Cambrian stratigraphy and, as noted above, paleontology.
Among his awards are the Righi Prize,
Bologna Academy of Science; Matteucci Medal,
Rome; the Mussolini Prize, Royal Academy of
Italy; Walcott Medal, National Academy of Science.

field of science which already has yielded the
transistor and other electronic miniatures,
according to university engineers. It is a key
tool, stronger than any other known, for probing
the fundamental properties of solids. The
engineers say its new features make it 40 per
cent more powerful than the only comparable
magnet which is at the Massachusetts Institute
of Technology in the United States.
THE BURTON MEDAL
The Electron Microscope Society of America
has recently announced that it has established
a Medal Award to be named after the late
Professor E. F. Burton of the Department of
Physics, University of Toronto.
"The Burton Medal may be awarded annually
to the person who, in the opinion of the Council of the Society, is adjudged to have made
(within the five years immediately preceding
the award) a most important contribution in the
field of electron microscopy." Candidates are
to be under 35 years and need not be U. S.
citizens although preference will be given to
work carried out in North America.
Graduate students working under Professor
Burton carried out some of the original development of the electron microscope in the late
1930's and early 1940's. The first successful
instrument in North America was built at Toronto
by Albert Prebus and James Hillier in 1938-39.
It is now part of the microscopy display at the
Ontario Science Center.
SUPERMAGNET IN AUSTRALIA
A supermagnet has been successfully tested
(August 1971) at the Australian National University, Canberra. Weighing only two tons but
containing 7000 parts, it uses the same amount
of electricity as a town of 40,000 people. A
computer controls its operation and the associated water cooling system which is large and
complex in itself. The supermagnet will lead
to further discoveries in a richly rewarding
APPOINTMENT TO THE DEFENCE RESEARCH BOARD
Dr. Larkin Kerwin, Vice-Rector (Academic) of
Laval University, Quebec, has been named a
Member of the Defence Research Board. He will
serve a three-year term.
Board Members represent other government
departments, the Armed Forces, and Canadian
universities and industry, serving somewhat
like the directors of corporations.
Dr. Kerwin was b o m in Quebec in June, 1924.
He became one of Canada's leading atomic and
molecular physicists after undergraduate studies
at St. Francis Xavier University, followed by
graduate studies at the Massachusetts Institute
of Technology and Laval University, which led to
Masters and Doctors degrees. Dr. Kerwin obtained his B.Sc. in 1944 and the two following
degrees in 1946 and 1949.
In 1946 he became an Assistant Professor
with the Department of Physics in the Faculty
of Science at Laval University. After further
graduate studies and a series of promotions, he
was named Vice-Rector of the Quebec university
in 1969. In addition to his teaching career,
Dr. Kerwin has been prominent in advancing
scientific education both nationally and internationally. He has been the recipient of many
distinctions and honours and has published
widely in his fields of interest.
FROM THE SCIENCE COUNCIL OF CANADA
SPECIAL STUDY REPORT NO. 13.
The Science Council Special Study Report
No. 13, entitled "Earth Sciences Serving the
Nation", was released on November 8, 1971.
Some major highlights and conclusions:
- Earth sciences are making important contributions to the Canadian economy and to many
other facets of our national and international
activities.
- This Study uses the term "earth sciences"
to include geology, geophysics, geochemistry,
soil science, physical geography and geotechnique. It documents not only the research and
development activities in these disciplines,
but also the nature of the extensive data
collection services which are required to define
the properties of the vast Canadian landmass.
- The Study documents for the first time
the levels of activity, expenditure and manpower
inputs, and future requirements of earth sciences in aiding scientific and cultural growth,
mineral resource development, the construction
and transportation industries, land and urban
planning, and Canada's overseas technical
assistance programme. In the course of this
extensive review, numerous recommendations are
presented to improve the coordination of existing activities and to promote the growth in
earth science activity which is required for
future needs.
Among the eighty-five conclusions presented
in the report are included the following:
- Canadian universities are not meeting
national manpower needs in most earth
science fields, both in terms of output
of professionals and the type of
graduates produced.
- Hard rock core storage libraries should
be operated by governmental agencies to
improve the effectiveness of Canadian
mineral exploration.
- The rates of completion of topographic,
geological, geophysical and other forms
of earth science mapping should be
accelerated to meet national needs within
the foreseeable future.
- Departments of education should encourage
the introduction of more earth science
into the science programmes of secondary
schools.
- A National Advisory Committee on Mineral
Resources Research should be established
to coordinate a national programme of
research directed at:
(a) lowering the risk elem^^t in the
search for mineral resources by increasing
the efficiency and effectiveness of
mineral exploration,
(b) promoting application of the most
efficient methods in mining and extraction
metallurgy,
(c) developing and promoting research into
the application of wise mineral policies.
- Increased attention should be given to
scientific investigations of land dynamics
and geological hazards. Mapping agencies
should markedly increase their output of
geological work oriented to environmental
and land use planning.
- Earth science activities, with natural
resource development, will form an
increasingly important component of
Canada's external aid programmes in the
years ahead.
- Universities should develop, in cooperation with industry, programmes to meet
the needs of industry.
- A comprehensive and multidisciplinary
programme of research into the origin and
evolution of the Canadian Shield should be
undertaken in Canada during the next
decade.
- The Canadian government should adopt
measures to encourage the mineral industry
to carry out, or support, more "in-Canada"
earth science research.
- The present level of earth science
activity by provincial departments is
insufficient to meet regional requirements,
and should be increased correspondingly to
reflect the present and potential revenues
derived from the mineral industry.
REPORT NO. 14.
Science Council Report No. 14, entitled
"Cities for Tomorrow: Some Applications of
Science and Technology to Urban Development",
was released on October 4, 1971.
Some of the highlights are:
- Throughout history, there have been those
who have questioned the quality of life
that is possible in the urban context.
"Cities are the abyss of the human species"
wrote Rousseau, in 1762. "At the end of
a few generations in them races perish
or degenerate, and it is necessary to renew them." Today, there are not a few
people who would agree with Rousseau, and
many more who, while disagreeing with the
depths of his pessimism, see the urgent
need for renewal in more than the bricksand-mortars-and-Civic-Centres sense.
- The Science Council can only hope thdt
constitutional and other discussions
having to do with the interplay among
levels of government will have the effect,
in good time, of reducing fiscal and
jurisdictional impediments to innovation
aimed at improving the quality of urban
life.
- The report indicates certain areas in
which "science and technology", even in
the more precise sense, can be applied
to certain urban problems. However, we
also have to consider science and technology in a broader sense: as an arsenal
of analytical methods and approaches,
including those of the behavioural and
social sciences, that are part of a multidisciplinal effort to encompass and understand complex problems of social reality,
as an aid to decision-makers.
Recommendations of the Council deal with:
- The use of sophisticated systems techniques and simulation models which should
be incorporated in the planning efforts
of all urban regions and Canadian
provinces.
- The establishment of a National Institute
for Urban Analysis.
- Public transportation and specific federal
and provincial cooperation in this field.
- Experimentation to make our communities
and our dwellings more livable.
- Countering the harmful effects of land
speculation.
- The construction industry's fragmentation,
under-capitalization, inadequate economies
of scale, seasonality, hazardous work
conditions, lack of effective utilization
of highly qualified manpower.
- Waste recycling and disposal.
- The funding of an independent network of
information bureaus to serve the citizen.
REPORT NO. 15.
Report No. 15, entitled "Innovation in a
Cold Climate: The Dilemma of Canadian Manufacturing", was released on October 6, 1971.
Background:
For the last eighteen months the Science
Council has had under way a study of Canadian
manufacturing industries that are science-based
or heavily dependent on science. To complement
its analysis of industrial and economic
statistics, the Council has surveyed 50 companies that are representative of medium and
high technology industries in Canada. In the
normal course of events the Council would have
waited for detailed analysis of this survey
and the publication of background studies. The
urgency of the situation the Council now sees
developing has, instead, prompted this interim
report.
Outline:
The report is in four sections. The first
amplifies the reasons for the Council's concern.
The next two outline the Council's concept of
technological innovation, and trace the origins
of the many impediments which now hinder the
process of innovation in Canada. The final
section suggests ways in which many of these
impediments may be removed. The Council concludes that a national industrial strategy is
urgently needed, and lists some of the components essential to the formulation of this
strategy.
Reasons for Concern:
- Manufacturing no longer seems able to
create the new employment opportunities it
provided during the sixties.
- Employment is now being lost in the very
industries in which most jobs were created in
recent years; generally, these are manufacturing
industries that are based on technology.
- Profits in these industries have progressively declined over the last six years.
Problems Identified in the Report:
- Inadequate technology base in Canada.
- Limited market size and market access.
- Poor climate for investment in manufacturing.
- Inadequate management skills.
- Improper location of industry.
- Tariff and non-tariff barriers to trade.
- Conflict between corporate goals of
multinational corporations and Canada's
national goals.
BARRINGER RESEARCH, INC.
Barringer Research has received a $180,000.
contract to produce ten heavy water monitors for
Canadian nuclear power plants. Successful evaluation of prototypes has prompted installation
of these electro-optical instruments for routine
process control. The low maintenance characteristic of these new spectrophotometric chemical
analysis devices allows them to be used to prevent the loss of costly heavy water (D2O)
moderator fluid.
Six units will be installed by the HydroElectric Power Commission of Ontario at its
Pickering Power Station east of Toronto. They
will continuously monitor minute variations in
the content of heavy water in the exhaust streams
of the reactor. An automatically switched
sampling procedure will record the level of D2O
above its natural background level of 140 parts
per million.
High-resolution, on-stream
analysis of up to 200 ppm more will be used to
detect leaks of D2O.

THE SPIRAL STRUCTURE OF OUR GALAXY, (International Astronomical Union Symposium No.
38), edited by W. Becker and G. Contopoulos.
Springer-Verlag, 1970, p.p. xiii + 478,
Price: $24.40.
To the uninitiated reader it might seem
strange that a Symposium on "The Spiral Structure
of Our Galaxy" would start with an extensive
section on the Spiral Structure of Other Galaxies. In fact, over one-fifth of the Symposium
was devoted to this subject. A reader with a
rudimentary knowledge of astronomy, on the other
hand, would expect most of such a Symposium to
be devoted to other galaxies since we see our
own only through a thick veil of obscuring dust
in the visual region, and without the benefit
of moderately direct distance indicators in the
radio region. It is thus a great pleasure to
read the papers in this Symposium and to see
the results - of much painstaking and often
brilliant research - beginning to give us, not
only a good theoretical picture of the spiral
structure of galaxies, but also a much improved
theoretical and observational picture of our
own.
This Symposium was divided into five parts.
The first, Spiral Structure in Galaxies, reflects the traditional way in which we use other
spirals to guide us to the objects and structure
that we should use to reveal the nature of our
own. The second, Observations of Spiral
Structure in Our Galaxy, discusses the success
with which we are now achieving this end. The
third section, Theory of Spiral Structure, discusses the increasingly successful attempts to
understand the nature of spiral arms themselves,
and the fourth, Comparison of Theory and Observations, shows the extent to which theory and
observation now match. The fifth section is
devoted to a Summary and Desiderata given by
Bok, Oort, Becker and Lin, and is an excellent
review of the state of the art.
It seems clear from the theoretical work
presented that the basic problem of spiral arm
formation and maintenance is close to solution,
as exemplified in particular in the papers of
Shu and Contopoulos. The gravitational solutions
to the problem, in particular the approaches of
the density wave theory and the computer simulated mass point models, are resulting in much more
satisfactory pictures of the spiral structure
than the magnetic field proposals did a decade
ago.
The improvement in observational knowledge
of our own galaxy is also considerable, both in
the radio and optical spectral regions. In the
radio region the motion picture studies of
galactic 21-cm line emission represent an unusual
and apparently highly productive method of studying the hydrogen space and velocity distribution.
Among the most tantalizing papers was that of
Mills who has succeeded in getting a "map" of
the spiral arms using the distances of pulsars
obtained from the dispersing effect of a
"uniform" interstellar medium on the radio
bursts from these objects.
In the optical region the survey work of
McCuskey, Lynga, their co-workers, and many
others is producing an impressive statistical
knowledge of the nearby regions of the Galaxy.
Other workers are producing significant results
more directly related to the spiral structure,
particularly in the Southern Hemisphere. In
this regard one must still agree with Oort's
comments that the Southern Sky is still largely
unexamined, and also add the wish that Canadian
astronomers had access to their own equipment
in this nearly virgin part of the sky. One of
the more startling(and still not credible)
results was that discussed by Isserstedt on
Stellar Rings. These are apparently ellipsoidal assemblages of relatively young stars,
with the minor diameter of the ellipsoid
thought to be a constant 7.1 pes. If these
are real, Isserstedt has essentially solved
the optical problem of the Spiral Structure of
Our Galaxy, out to the far side. Perhaps one
point lacking in the book is a more extensive
reporting of the discussions following the
papers, but this is a minor fault since the
best discussion at conferences is always
informal. On the whole, the editors have done
an excellent job, as have the organizers of the
Conference. All in all, the papers at this
Symposium were stimulating and usually good.
Perhaps the words of Bok in his "Summary and
Outline" give the best description:
"This Symposium has produced several
ground-breaking papers, a large number
of new and solid contributions to our
knowledge and understanding of spiral
structure, and there have been some
excellent peripheral papers. But we
must admit that there have also been
a dozen or more poor and irrelevant
papers...."
Any Symposiun containing 86 papers in which only
a "dozen or more" are described as poor is very
worthwhile as most of us know! This Symposium
was particularly good, and the book containing
the papers delivered is a must on all astronomical library shelves, and, despite its price,
should probably be on the shelves of all those
studying the Galaxy.

THE APPLICATIONS OF HOLOGRAPHY, by H. J.
CaulfieId and S. Lu. John Wiley & Sons,
1970, p.p. xiii + 138, Price: $9.95.
In 1948, Gabor originally conceived of the
wavefront reconstruction process as a means of
improving the imagery of the electron microscope. The advent of the gas laser, providing
a bright, highly coherent light source, coincided nicely with the introduction of the offaxis reference beam method by Leith and Upatnieks, and has produced a renaissance in
holography during the last decade. And yet,
holography's best known application - making
lifelike images in laser light - may turn out
to be its least important one.
This new book endeavours to give a survey of the
applications of holography. It covers such areas
as 3-D and 2-D photography, computer generated
holograms, optical data processing, interferometry, information storage, microscopy, motion
pictures, and television.
Written for the non-holographer, with physics
and mathematics kept as simple as possible, this
book serves as a good introduction to the subject. The short but useful appendix on how to
find further reading helps fulfil the author's
aim of getting the right information to the
right people. It is obviously not intended as a
textbook, but it would be a useful addition to
library shelves. As a reference book, however,
it is hampered by the very short subject index
and complete lack of author index.
The quality of the printed text and illustrations is excellent. A minor criticism is
that the figure captions do not always agree
with the description given in the text. For
example, on p. Ill, "Double exposure holographic
interferometry of a plastic bottle before and
after it was compressed with a vice", differs
from "double exposure hologram of a plastic
bottle before and after it was pressurized with
air", p. 110.
While the future of holography is discussed,
very little mention is made of areas predicted
by Gabor to be important; namely, the application
of the holographic principle to sound waves or
"vision by ultra sound", which can be used in
medical diagnostics by making tumours, fetuses,
or blocked arteries visible.

ISOSPIN IN NUCLEAR PHYSICS, edited by D. H.
Wilkinson, Wiley Interscience Division (New
York); North-Holland Publishing Company
(Amsterdam); p.p. 751, Price: $43.50.
This is a very useful, informative, and handsomely produced book. Following a short historical introduction by the editor, thirteen chapters
by well-chosen authors provide a very complete
account of what was known about isospin in nuclear
physics up to the time of publication in 1969,
with emphasis on the theory and properties of
analogue state resonances.
The book roughly divides into two parts.
Charge independence and charge symmetry of the
two-nucleon force is reviewed by E.M. Henley and
nuclear symmetries by J. P. Elliott. Then the
roles of isospin in beta decay, e.m. transitions,
and isospin purity of low lying states are discussed by R. J. Blin-Stoyle, E. K. Warburton and
J. Weneser, and J. M. Soper, respectively. The
chapter on e.m. transitions makes a good attempt
at systematizing a wealth of data, by enunciating
a set of rules and confronting them with the
evidence. The first part ends with a chapter on
isospin distributions in nuclei by J.B. French.
At page 300 begins a review of systematics
of Coulomb energies by J. Janecke, containing
data up to June 1968. Then, G.R. Satchler discusses the isospin dependence of optical model
potentials, D. Robson describes the theory of
nucléon induced analogue resonances, and A. M.
Lane discusses line broadening and fine structure
in analogue states. To finish up, Stanley S.
Hanna reviews the e.m. decay of analogue states,
J. P. Schiffer the role of isospin in transfer
reactions, and G. M. Temmer its role in nuclear
spectroscopy.
A noteworthy detail of organization of the
book is the arrangement of references. Throughout each chapter there is a footnote indicating
the page of text (at the end of that chapter)
where the references can be found. In addition
there is at the end of the book an over-all
author index and a reasonably complete subject
index. This combination makes it a book that
is easy to read, and easy to refer to. The
density of misprints appears to be remarkably
low.
The chapters are well written and authoritative. It is a book that should be in every
nuclear physics laboratory, and that promises
to have a long half-life.

THIN FILM PHYSICS, by 0. S. Heavens.
1970, p.p. 151, Price: $7.95.
Methuen,
After a short introduction there are seven
further chapters devoted to the methods of preparation and examination of thin films, their
growth and structure and their mechanical,
optical, magnetic and electrical properties.
There is a list of 42 references at the end of
the book.
The author states in his preface that the
monograph is not intended to provide in-depth
studies of any particular area but rather to
provide for the general reader or new-comer to
the field a general background from which
interests in individual directions may develop.
The book is easy to read and provides a general
background to the physics of thin films which
are supported on a substrate. Consideration is
not given to unsupported thin films prepared by
chemical or electrolytic etching. The section
on electron microscopy and diffraction contains
a number of inaccuracies, for example, the difference between dynamical and kinematic theories
of scattering is not mainly concerned with the
assumed geometry of the scattering centres and
with boundary conditions but with how heavily
the main beam is scattered. The figure showing
the Ewald sphere construction is inaccurate
because the incident and scattered beams are
not normal to the sphere. It is difficult in a
book such as this for the author to decide what
to include and what to omit particularly with
regard to references. However, 42 references
cannot be considered to be adequate especially
when the most recent references for three of the
chapters appeared in 1962 or earlier. If the
reader wishes to read about thin film physics
without pursuing further any aspect of the subject, then this book is satisfactory. If, however, he is likely to want to probe deeper after
his interest has been aroused, then other more
expensive competitors with more extensive
references would be appropriate.

THE NATURE OF LIGHT, by Vasco Ronchi (translated
by V. Barocas). Heinemann Educational Books,
1970, p.p. 288, Price: $24.00.
This is an English translation of the 1952
edition of Storia della Lucae, written by the
famed Italian physicist in 1939. It traces the
historical development of the study of light from
Graeco-Roman times to the triumph of the wave
theory in the nineteenth century. The contributions of Euclid, Hero, Alhazen, Kepler, Galileo,
Grimaldi, Newton, Huygens, Young, Fresnel, and a
score of others are described and evaluated.
Ronchi's approach is chronological and
methodical but never pedantic. He reviews the
major treatises of his subjects, using numerous
quotations which are well-chosen both to illustrate clearly the point under discussion and to
enliven the text. For example, Fermât's letter
to a colleague provides a fascinating account of
how he was led to establish his renowned Principle. The Chapter on Newton's Opticks is
particularly complete, but unusual. The weaknesses in Newtonian thought are stressed in order
to demonstrate that, although Newton had struggled
to prove the corpuscular theory, he failed, even
in his own opinion. However, in the eighteenth
century, others embraced this theory and through
his reputation were able to raise it to an unquestionable scientific dogma.
The problem of the nature of light always has
provoked philosophical as well as scientific
interest and Ronchi concerns himself with both
of these aspects. He emphasizes that from the
earliest work, a distinction was made between
the latin words lumen and lux,that is, between
an external physical agent and an internal
psychic effect. Gradually, this difference was
forgotten and confusions arose that persist today.
The subjective nature of colour had been so suppressed by the disciples of Newton that even the
poet Goethe was prompted to write 1400 pages in
defence of this concept.
In summary, the book is an engrossing and
critical survey of the classical theories of
light and deserves the attention of any physicist
interested in the history of his science. Unfortunately, the unjustifiably high price will keep
it out of most personal libraries.

There is a research furnace with
± VyC uniformity, fast response,
process repeatability, stability of
±'/4°C and capability for large
process tubes.
The Mini-Brute is a
sophisticated research furnace.
Fifth generation in performance. It
was designed and developed to
satisfy the critical requirements of
materials, development and
diffusion processing in the
electronics industry.
Thermco's new furnace
will give you 14 inches of flat zone
at ±V2°C between 800°C and
1300°C using a 31/4 inch O.D.
process tube, or 12 inches of flat
zone at ± 1°C using a large
4V2 inch O.D. tube. For low
temperature use, the furnace
provides 12 inches of flat zone at
±2°C from 400°C to 800°C using
any tube size up to 4 V 2 " O.D.
Fast heat up, controlled
cooling and consistent process
repeatability cycle after cycle. This
is your answer to the tough
problems in high temperature
research.
The Mini-Brute features
Thermco's exclusive Ana-Lock
controller. A three zone computerized instrument : all solid state.
Each zone has its own proportional
band and automatic reset. All
settings by digital dial to within
i/2°C. The controller is a module
that is easily removed for
maintenance purposes. All control
functions are on replaceable
printed circuit boards.
A cartridge type heating
assembly employs a continuous
helically wound high temperature
alloy rod mounted in high purity
insulation. The element is zoned
for maximum temperature
control. The unique heating
chamber design incorporates
