T~XT: Unlike the spectra of tetra- and hexaethyl derivatives, the infrared
absorption spectrum of triethyl germanium, that of triethyl tin, and that
of triethyl lead oxides (Et 3MOMEt3) of corresponding ethylates (Et 3MOEt)
and triethyl tin peroxide (Et 3SnOOSnEt3), which were examined here
(IM - Ge, Sn,1Pb; Et = C2H 5), display intense bands (Ge - 856, Sn - 776,
.Fb - 638 cm- ) which are suited for analytical pur~osies and can be
attributed to the asymmetric vibrations of the M-0-M'group. It has been
shown that the force constant of tlizi M-0 bond can be estimated under
certain conditions relatively to the valence angles.of the M-O-M group.

Vibration spect~ra of organic B117/B186
The resulting values can be used to estimate the vibration frequencies.of
the 14-0 bond in triethyl germanium, triethyl tin, and triethyl lead k
ethylate. The vibration frequency of the Pb-O bond in an Zt3PbOEt mol:ecule
corresponds obviously to the asymmetric vibration frequency of the PbC3
group. In the range about 590 cm-1, the spectrum ofjEt3SnOEt shows a
band of medium intensity, which can be attributed to,the vibration of sn-O.
The question whether the weak band detected in the Et3GeOEt spectrum near
650 cm-1 can be assigned to the vibrations of the Ge-O bond has not yet
been answered. For analytical purposes, however, the intense bands found
in the spectra of eth,-rlates around 900 cm-1 and between 1050 and
1100 cm are more important. The 550 cm band in the spectrum of tri-
ethyl tin peroxide and the 790 cm-1 band in the spectrum of triethyl
silicon peroxide must be attributed to the stretching vibrations of the
Sn-O and Si-O bond, respectively. The characteristics of *ahe spectra under
examination made it possible to investigate the mechanism underlying the
oxidation of hexaethyl diplumbane and hexaothyl distannane as well as the
properties of triethyl tin peroxide (Ytlv)zAir~Alleknaiidzo'v.,,Zt 7N.;hTy-shinsk1:y,'-.9

and triethyl-lead perbenzoite are related in this article. The peroxide compounds
were easily hydrolyzed by water with the formation of tridthyl-tin monohydroxide
(or triethyl lead monohydroxide) and hydrogen peroxide (or the corresponding hydro-
peroxide) at room temperature. The results of the analysis are presented in a table.

ABSTRACT: This is a continuation of earlier work by the authors (Preprint OIYaI,'
R-2495, Dubna 1965 and elsewhere) on neutron scattering by lead at neutron energied
down to.7-5 kev, where it was indicated that the estimate Mn < 20 x 10 42 CM3 for the
neutron electric polarizability coefficient, previously obtaJ7ned by R. M. Thaler . 11
(Phys. Rev. v. 114, 827, 1965) in scattering by uranium, can be appreciabj~y lowered. .1
Lead was chosen in the present.investigation bece-ase it has no strong neutron reso-
nances in the investigated energy range up to 26 kev, thus avoiding the ambiguity
connected with neglecting the role of the resonances. The measurements were made-
with.the OIYaI pulsed reactor by the time-of-flight method with a 250 m base and with
an en6r6y resolution ranging from 20% at 1 kev to 100% at 26 kev. The effective
ener&r was determined at each point by numerical Integration with account of the re-

intensity of the neutrons scattered by a hollow lead cylinder of 10 cm diameter andt;z
1 cm wall thickness was measured simultaneously at all energies and 9 values of the.,
scattering angle from 30 to 1500. Reduction of the experimental data yielded the
estimate an - (0-3 1 9.2) X 10-42 cm3. A more accurate estimate of the polarizabill-
ty is obtained by simultaneous reduction of the present data and published data on*.i-
scattering by lead in the 50 - 160 kev interval. Such a reduction yields Mn = (0-71
* 5-4) X 10-42 CM3. It is thus concluded that, with a probability -68%, the values'.
ofan range between -4-7 and 6.1 (X 10-42) cm3 and are of the same order of magnitude
as the theoretical-ly expected value (1 - 2) X 10-42 cm3. The authors thank F. L. -

TITLE On the S_ca_ffe=1ng of Fast Neutrons by the COULOMB Field of a
Nucleus.
PERIODICAL Zi;.rn.eksp.i teor.fis,~I, fasc.4, 726-727 (1956)
Issued: 1 / 1957
At first some previous works dealing with this topic are mentioned. In the
present work the angular distribution of the fast neutrons which are emitted
from the reactor and are scattered by Pb and Cu is discussed. The data given
below are preliminary results. The neutron bundle was limited by a steel
2
collimator to an extent of 0,9 x 3,6 cm . At a distance of 10 cm from the end
of the collimator a scatterer consisting of a Pb- or Cu-plate of I cm thick-
ness was fitted. The detector, which was arranged at a distance of 325 0m
from the plate, was a photomultiplier with plastic scintillator (ZnS in plexi-
glass) with low sensitivity with respect to -rays and neutrons of an
energy of less than 1,5 MeV. Before work starfed, the effective total number
of electrons impining on the scatterer was determined, which made computation
of the differential scattering cross section a(G) possible. The effective
energy of the neutrons determined from the cross section of nuclear
scattering amounted to from 3 to 4 MeV.
The results of measuring of the angular distribution are shown in form of a
diagram; the curve was constructed according to SCHWINGER's theoretical
formula. From measuring results it may be seen that anfincrease of the cross

section, which is-characteristic of SCHWINGERIS scattering, is observed for
Pb(Z = 82) within the range of the angles 4, 20. The value of the cros,s
section agrees with theoretical results obtained by SCHWINGER and SAMPLE.
For Cu (Z = 29) the increase of cross section is within the limits of
measuring errors.
In the work by R.G.P.VOSS and R.WILSON, Phil.Mag.,ser.8, 1, 175 (1956) which
was recently published, the authors observed a SCHWIN-Gd-scattering of
100 MeV neutrons by uranium. The dependence of the cross section on the
angle resembles the theoretical curve, but numerical values of 6(9) are not
mentioned by the authors.
In conclusion it must be mentioned that - as is shown by evaluations - in
the case of an existing "polarizability" a ~ r3 of the neutron (r - ex-
tension of the nucleon), the additional contribution to the cross section
of scattering of neutrons by heavy nuclei attains a considerable magnitude.
This effect increases with reduced energy, but more carefully carried out
experiments are necessary for determining this effect.

ABSTRACT: The latest works on the scattering of fast electrons by hydrogen
confirm the conclusions of the meson theory concerning the ex-
tensive distribution of the electric charge in the nucleon. This
charge distribution is due to a "cloud" of charged masons round
a central nucleus. Under the influence of an exterior field the
distribution of electric charge in the nucleon will change.
Above all, a polarization of the homologously charged meson
cloud and of the nucleus in the nucleon can be expected and the
neutron.will_,,then probably receive an induced electric dipole
moment p - aE, a fact which becomes apparent by an abnormal
behavior of the differential cross section of the scattering of
neutrons by heavy nuclei into small angles. If it is assumed

In consequence of electric polarization the neutron is sub-
jected to an additional scattering of the GOUWMB field of the
nucleus. Polarization scattering attains its maximum if the
collision parameter is restricted by the condition R d a.

AB.iTRACT: In order to achieve a precise definition of the decay scheme,
further investigations of the y-y and 0-y coincidences were
conducted. The measurements were taken by means of luminescence
spectrometers. They were connected with a coincidence cir-
cuit with a resolution of 2.1o-7 see. The coincidence spectra
with the y-lines of 605, 797, 1170 and 1370 keV were investi-
gated. The experimental evidence substantiated the existence
of the transitions from 605-797, 605-1370, 605-570, 797-570
and 117o-8o2(797) keV. Also the cascade transitions from
605-104o an~ 1170-475 keV were demonstrated. The transition
from 605-475 keV was not found. The analysis of the cot-ridence
spectrum shows that the hard part of the ~-spectrum coi,icides
to a higher extent with the y-line of 797 keV than with the
Card 1/3 line of 605 keV. This agrees with results from reference 10.

Investigation of Cs 13 ~y t1B Coincidence Method SOV/46-22-7-14/26
In this paper the hard range of the y-spectrum of Cs 134 was
investigated. The photo peaks of the y-rays of 1640, 1750,
1870, 196o and 204o keV were confirmed to 6exist. The -intensi-
ty of all y-lines is of the order of 10- quanta per decay.
The experimental data obtained. concerning the y-y coincidences
and the measurement of the hard part of the y-spectrum of Cs154
do not contradict the decay scheme given b.~, Poster (Foster)
and Wiggins (Ref 6) with respect to the hard y-transitions
as given in reference 13. Only the transition at 4*15 keV
aGcording to these measurements takes place between the levels
of 1644 and 1168 keV and not between the levels of 187o and
1368 keV (Ref 6). From the results concerning the P-y--co--
incidences it can be concluded that part of t )-transitions
with 137o keV leads to the ground state of Ba~!4. The q-tiantal
characteristic of the level of 137o keV is 3-. The y-transi-

that the inert mass of antiparticles must be positive. In
this case the hypothesis of a negative gravitation mass of
antiparticles is apparently in contradiction to the general
relativity (principle of equivalence). 2) The a.ssumption
that the gravitalon mass of antiparticles is negative would
lead to additional difficulties in connection with the existence
of bosons- 3) To assume the existence of an antigravitation
would necessitate radiial clianges of present physical notions.
Direct experimental determination of the sign of the gravi-

of positrons in the gravitational field of the earth) would
be moft desirable. The authors thank Professor D. I. Blokhintsov

ABSTRACT: The bubbles which form the particle tracks in a bubble
chamber are light scattering irregularities. They
may be looked upon as spherical lenses having a
refractive index which is different from that of the
surrounding medium. The optical properties of such
irregularities are determined by theirrelative refractive
index and radius of curvature (Ref 1). In a bubble
chamber, the refractive index of the liquid J.-, greate--
than that of the bubble and, therefore, the latter
behaves as a negative lens. The incident light is
therefore refracted in the bubble and produces a virtual
image of the source of light near the image of this "lens".
Rays refracted by the lens and entering the objective

of the bubble. It is theref3re of interest to consider
the effect of the difference in the position of the
bubbles and the corresponding images of the source of
light. For paraxial rays incident from infinity the
distance from the centre of the spherical lens of radius
R to the image is given by:

where An is the difference between the refractive
indices of the liquid and the bubble. Each point of
the source of light is imaged near the focus of the
spherical lens, and the entire source is imaged with a
magnification given by 0 Sf fl/L where L is the
distance from the source of light to the bubble. Clearly,
in the case of bubble chambers and particularly in the
case of liquid-hydrogen bubble chambers in which tin
is small, the spatial separation of the bubbles and the

been found with the aid of a model that aberration
and diffraction effects are negligible. A large-scale
photograph was taken of bubbles in a propane chamber
using the apparatus shown in Figure 1. The illuminating
system consists of a source of light S , an opaque
screen A and a diffuse reflector B . Figure 2 shows
photographs of electron tracks in the pg8pane bubble
chamber. The electrons were due to Co sources.
in Figure 2, photograph (a) was obtained with a single
source (a small hole in a screen); (6) with two holes;
(B) with three holes; (11,) and (6) with a ring source.
From a knowledge of the geometry of the experiment it
was possible to estimate the diameters of the bubbles.
They were found to be between Q1 and 0.11 nun, depending
on illumination conditions. It is concluded that the
recorded bubbles are in fact it.-.ages of the source of
light. The spatial displacement of the image of the
source relative to the centre of the bubble is not small.
Thus, in the case of liquid hydrogen the quantity V

TEXT.* It was shown in Ref. I that when bubble-chamber tracks
are photographed, the object which is actually photographed is
the virtual image of the source in the bubbles. The
refractive index of the vapour in t" bubble is srhaller than
the refractive index of the surrounding liquid and hence the
bubble is divided into two zones. The bubble constitutes a
negative lens for rays incident at angles smaller than the
angle of the total internal reflectionand a convex spherical
mirror for rays incident at angles greater than the angle of
total internal reflection. This is illustrated in Fig. 1.
The point source S 0 is located at infinity on the left of

where n_
,, is the refractive index of the liquid and
n.., is the refractive index of the vapour.
For the reflected rays Y2 = 2(90 0 -12) . The objective
of the photographic camera receives a narrow pencil of rays
whose aperture is defined by the diameter of the entrance pupil
of the objective and the distance to the working volume of the
camera. For an o6jective with a focal length of 50 mm, a
relative power a!" 1.20 and a distance to the workina volume
of 500 mm, the aperture of the pencil is about 0.5 - It
follows that the image formed by the objective is due only to
a very narrow pencil of rays,. Such a pencil will experience
only paraxial aberrations, i.e. astigmatism and distortion.
In order to confirm the above theory of image formation, an
exp(riment was carried out using two sources of 'Light located
symmetrically with respect to the objective-bubble axis. In
this geometry each bubble forms four virtual images. two of

which are produced by the refracting zone and two by the
refle;.ting zone. The distance between each corresponding
pair of images, which is equal to 2H I and 2H 2 in the two
cases, respectively, depends on the radius of the bubble. V
For all bubbles, 2H 2 is determined by the relative /1%

In the experiment, an objective having a focal length of
240 mm and e. relative power of l.-16 was employed.. It was
found that the above theory describes the experimentally
obtained results to a high degree of accuracy.

PERIODICAL.- Pribory i tekhnika eksperimentav 196o, No. 6,

TEXT.- It was shown in previous papers by the present
authors (Refs. 19 2) that when particle tracks in bubble
chambers are photographed, the object which is photographed
is the virtual image of the source in the bubbles. The
experiment described in Ref. 2, in which two sources of
illumination were employed will also nrovide information about
the rate of growth and the rate of upward drift of bubbles.
The experiments reported in the present note were similar to
those described in Ref. 2 (see the previous abstract of this
issue), except for the sources of illumination. Two pulsed
lamps were used to illuminate the two sources using a delay
of 7, 14, 22 and 30 ps, respectively. A photograph of two

successive flashes of the lamps was obtained on each plate.
During the time between the flashes each bubble increases in
size and drifts upwards. The growth of the bubble leads to an
increase in the distance between the dots in the horizontal
direction, while the upward drift leads to a displacement of
the dots in the vertical direction, A typical photograph
is shown in Fig. 1. The radius of the bubbles was measured
by the method described in Ref. 2. In the four series of
measurements which were carried out the initial radius was
between 0.1 and 0.2 mm and the final radius between 0,2 and
0.36 mm. According to Seiiz (Ref. 3), the radius MM is
related to the time in sec by the formula r Ct . The

value obtained for the constant is C (5-8+2 )10-

On the Rate of Growth and the Rate of Upward Drift of Bubbles
in a Propane Chamber
'7he errors indicated represent maximum deviations. According
70 Plesset and Zw�ck (Ref. 4), the constant C for propane
has the theoretical value of 0,17. The rate of upward drift
for the above range of bubble radii was found to be 0.036
and 0.117 mm/sec. It is clear that the rate of up-ward drift
is appreciabfy greater'than the rate of growth of th'e bubbles,
i.e. during its growth each bubble is displaced through the
sarrounding medium. This fact was not taken into account by
Seitz!'fRef, 3). The heat exchange between the bubble of
liquid, which determines its rate of growth, will be greater in
the case of a moving bubble. This will lead, in the case of
the present experiment q to a discrepancy between experiment
and theory, as xndicated above. Further work is being carried
out in this connection.

the Second Geneva Conference (1958). Inside the core the neutrons have
energies of more than 100 kev which they lose almost completely in passage
through reflector and shield. In the outer layers of the shield, their
mean energy does not exceed some tens of ev. In the kev range (-Pn~50 kev)
spectra were measured for the most important beams and channels. For the
other cases, they were determined from threshold reactions. The soft part
of the spectrum within the reflector was determined from the spatial
distribution of neutrons with E!~15 ev, recorded with gold resonance indi-
n
cators. The total neutron flux was determined only at the points where
the Pu 239 fission cross section was constant, Direct neutron spectrum
measurements were carried out in a vertical (OK-70) and a horizontal (B-3)
channel using (He3+Ar)-filled ionization chamber in the first case and the
neutron tzanenissiim method with n-hexane in the second. The neutron
spectrum of the horizontal channel was also determined by photoemulsions,

present note the authors make use of their theory of the growth of
t bubbles (FIAN, A-131, 1961) to calculate this di'splacement and
estimate the distortion of tracks. Explicit formulae are given
which may be used to compute these effects. In a typical hydrogen
chamber (N.C. Barford, Progr. in Cryog., 2, 196o, 88) a spurious
radius of curvature due to unequal displacement of tracks along
their lengths was found to be of the order of 20 m. The
distortion may be reduced either by ensuring that the bubbles

growth of the bubbles. In practice it is always possible to
reduce the distortion by a suitable choice of the working
