ABSTRACT; In the course of the evaluation of emulsion piles exposed in
the geographical latitude of Moscow at a height of 30 km, a
star (20 + 15 + 59P) was recorded, which had been produced by
an interaction between a cosmic radiation proton and an
emulsion nucleus (Fig 1). In the present paper the authors
report about an analysis of the angular distribution of charged
particles in this star. The energy of the primary particle
was determined as amounting to
F = (19 +5M).103 Bev. Accordin.- to Heitler and Terreaux

the authors (1~, h ~ 35) cannot be explained by the Heitler-
Terreaux theory. Figure 2 shows the differential angular
distribution of the shower particles in this star. The histo-
-ram has two different maxima. For comparison, the curves for
isotropic distribution (in the ems), for Heisenberg distribu-
tion., and for distribution according to Landau are plotted.
It was found that, if it is assumed that in a nucleon-nucleus
collision the angular distribution does not deviate consider-
ably from that of the mesons formed in a nucleon-nucleon
collision, the angular distribution observed can be explained
neither by ffeisenberg~s (Fef 6) nor by Landau's theory (Ref 7).
Figure 3 again shows a histogram of tne angular distribution
of shower particles in ihe laboratory system. The curves
1,2,3,4 (in the cms' successively show Gaussian, isotropic,
and anisotropic distribution for each of the two maxima
separately (in consideration of the energy spectrum of the
produced particles and on the assumption that they are mono-
energetic). It may be assumed that the two maxima observed in
the differential angular distribution originate from a meson

emission of two unconnected centers, which move in different
directions in the cms: 30 particles in the narrow and 29 in
the diffuse cone. Pigure 4 shows the integral angular distri-
bution of such a star. The authors then give a report on an
'nvesti-ation of further 11 stars with E > 100 Bev, which
prim
have the same characteristic anisotropy. Figure 5 shows the
total histogram of these 11 showers with the two maxima.
Table 2 shorts the results of an analysis of all investigated
showers (Kr 10 gives the data of the first star described in
detail). In conclusion, the angular distribution of the -ray
and black traces of the (35 + 59P) star is discussed on the
basis of figure 6. There are 6 figures, 2 tables, and 12 refer-
ences, 8 of which are Soviet.

theoretical considerations for a number of showers (the ex-
perimental data were obtainod from references 4-8); the
values for y. and K for the variants a) and b) at variou3 con-

It was found that, under the a3sumption p,5~~ 1, an evaluation
of the energy characteristic (y. and K) in showers, of which
only the angular distribution of the secondary particles is
known, is possible. The thus obtained y.-values agree well
with those which have been obtained on the assumption of an
exponential energy spectrum of the produced mesons (Ref 7).

ABSTRACT. An investi-ation of the angular distribution of thin traces in
the show.2rs raccrded in photographic, emulsions -furnishes the
basis fo~ the high degree of excitation of the colliding nuc-.
leons, ea~,h .5f whi,,th separately emits pions. Such a hypothesis
was brought forward by several authors (Ref 4). Further exps-.
rimental inv~_stigations, however, showed that the coefficient
of nortelasticity the fraction of energy transmitted to
the produced particles) in most cases is of the order of nzag-
nitude 0,15 to 0.20, which cannot be explained by the model of
two centers .-f me3on emission formed by the nucleons. F~jrther

average value of the energy of the secondary particles. Form-a-
las are written down fcr the differential and integral anLrular
distribution. in a diagram the curve given by the integral ar-
gular distribution is compared with the distribution of the
shower particles of the star 35 + 59 p. Agreement is fully sa-
tisfactlory. Such comparisons are, by the way, possible for any
stars., The production of the shower particles may thus be ax-
plained as follows; 1) In the case of high multiplicity the
anoular distr *ibution of particles (produced in the first staE;e
of the colliaion between the particle and any part of the tar-
C-Fit-nucleus) is nearly isotropic, in the center of mass system.

that in the emulsion used by the present authors t e spurious
scattering n follows the power law n = 0a00 t - , It is thus
found that provided the spurious scattering is allowed for, the
energy of charged particles can be determined by the multiple
scattering method in the region of 10 GeV. At this energy the
.c-nurious scattering is negligible for a cell size of t = 4 mm.

PERIODICAL: Vestnik akademii nauk Kazakhskoy SSR, 1960,ANO. 7, pp~~ 33 - 38
TEXT: The author describes some variants of a magnetic trapping ves-
sel which, he suggests, may be of use in studying the fusion reaction of
light nuclei (deuterons, tritons, etc.) when they mutually collide. Such a
vessel, in which the density of the reacting particles increases rapidly
with time, would be suitable for carrying out controlled fusion of lightel-
ements with a large gain in energy. The vessel consists of a toroidal cham-
ber in which, for the sake of argumentg a magnetic field of equal intensity
at all points is present, The two beams of light nuclei, accelerated to an
equal energy, are directed against each other, and the spatial charge inaxy
section of the toroid neutralized by a third beam, the density of the cur-
rents of the negatively charged particles being roughly equal. The author
examines the equations for the movement of particles in the toroidal magnet-
ic chamber and shows that the particles will drift due to twisting of'the
lines of force of the magnetic field and to the inhomogeneity of the magnet_

ic field within the toroid, and that the absolute speed of the particles
varies little. To reduce drift of the particles, he suggests the use of a
magnetic field of variable sign., which varies along the toroid; this may
well be of use for plasma also. The use of magnetic mirrors (formed, e.g.,,
by spiral currents) to reduce drift is not considered promising. Other
variants discussed consist in the use of a transverse magnetic field and
pdwerful focusing by magnetic lenses, and the system of particles which
"catch each other up". In this method the deuterons and triton5 are intro.-
duced into the transverse magnetic field in such a way that they move along
the same orb-it. There are ~: diagrams and 2 Soviet references.

A direct comparison with the experimental angular distribution in the

tion is consIderably less anisotropic., This discrepancy does not Occur if
one assume., chat the energy spectrum of the mesons produced is Similar to
the spect,rum following from the Heisenberg theory (Ref- 1). (2) The hydro-

p?ars to be shifted into the region of high values of the
transverse momenta; this is the consequence of an extremely hard energy
spectrum of the m~--sons produced, such as is predicted by this theory. in
a more exact variant of this theory as well as in the homogeneous variant
(Refa~ 14, 112) the distribution of the transverse momenta coincides with
that obtained experimentally, (3) The Fermi theory (Ref, i5) in -Uhermo-
dynamic approximation does not lead to transverse momentum distributions
agreeing with the experiment, (4) The transverse momentum distribution
following from the Heisenberg theory (Refs. 1,10) agrees satisfactorily
with the exDcriment-, The energy spectrum of the Droduced particles
resulting from this theory has been experimentally verified (Refs- 2~9)
The angular distribution does not follow immediately from the theory, buts
it was qualitatively described by Heisenberg, who proceeded from the

showers produced by cosmic ray particles with energies exceeding 1011 ev.in the
stratosphere. Characteristics of showers in the energy ranges 1011 ev *-' E 44~1012
ev and E > 1012ev are compared with various theoretical concepts. To explain a
number of peculiarities in angular distribution (e.g., occurrence in some showers
of distribution with two peaks), It is proposed to take into consideration the
role of produced particles (antinucleons, 1-mesons) in generation of additional
particles at secondary collisions inside the target-nucleus, The angular distri-
buzion of shower particles produced by multi-charged particles is also analyzed.

(25-300) predominating; in many showers of smaller multiplicity, however,
angles of emission of 70 were reached. The experimental results are
compared with those obtained from the theory of peripheral interaction in
single-meson pole approximation. Since the multiplicities were small, it
was necessary to take the fluctuation of the particle numbers into account,
(cf. 71. 1. Podgoretskiy et al. ZhETP, 29, 296, 1955). Further, the
dependence of the form of angular distribution of shower parti;les on
their velocities of emission, and on the angle of emi3sion of the excited
nucloons in the c.m.s. is studied, The comparison of experimental and
theoretical results has predominantly a qualitative character. The
calculations made by other authors according to the theory of peripheric
inter.action (based on'the perturbation theory) in sTngle-meson pole,
approximation gave for nucleon-nucleon interaction at 9 Bev and 200-300 Bev
6ood agreement with experiments, which shows that peripheric interaction
at these ener.-ies plays an important role. In this approximation, the

results of the investigations described here may be summarized as follows-
The mass of the excited nucleons and the multiplicity of th6 generated
mesons depend on the direction of motion of the excited nucleons in the
C.M.S. The form,of the angular distribution of the shower particles in'
'the laboratory system depends on the velocity and direction of motion of

.ABSTRACT: The paper is primarily a general review of recent experimental work,.
titainly by Soviet scientists, on nuclear processes occurring at very.high energies,,
(E t>Mc2), specifically, in the 1011,to 1013 OV range. It is noted that nuclear-
processes in this energy range are characterized by very slow variation of their:
characteristics (cross section, etc,) with energy, which makes it imperative to en-;
compass a wide energy interval in order to discover trends and regularities. Men-.,,
.tion is made of some theoretical evaluations as well as confirming or-independent
.experimental studies by means of pellicle stacks, ionization calorimeters, various
counter and chamber arrays,and spark chambers (the merits of the last are stressed),.-,-.

aimed at determining gamma-ray spectra, particle distribution, shower particle Spec-:,:
tra, etc. The f ire-ball model is discussed in connection with some of the briefly
described experimental results and theoretical hypotheses,, Mainly, only tragmentary,4
or general data are given. Among the experimental problems suggested for further
study in the immediate future are measurement of the inelasticity coefficient and
its variation in magnitude in nucleon-nucleon interactions, determination of the
variation of the inelasticity coefficient and interaction cross section with the
;atomic number in nucleon-nucleus interactions, clarification of the role played by
the f ire-ball mechanism in nucleon-nucleus and pion-nucleon interactions,, determi- :J
nation of the significance of. the process of 'pion production via decay of isobars .1-
and comparison of neutral and charged pion production processes, determination-of
.the relative importance of central collision processes interactions at different
energies, and determination of the fraction of different strange particles created
at different primary particle energies. It is hoped that solutions to some of these
problems will be provided by the new.cosmic ray research equipment now being in-
stalled at mountain altitudes in the Soviet Union. These installations consist of
,large Wilson chambers in a magnetic field and several trays of.ionizati6n calorime-
ters. The largest installation of this type is now being, constructed in the Georg-
ian SSR at an elevation of 2200 meters; this will be equipped With 2 X 2 meter Wil-

ABSTRACT: The purpose of the work was to study the depender-le f
the ionization characteristic (blob density) on the particle eyfbrcjy.
(in rest-mass units). To this end, the authors carried out special
measurements of the relative ionization in tracks of protons of
energy 2, 3, 4 and 5 BeV and pions of 3.8 BeV energy, in stacks of

NIKFI-R emulsions irradiated at the Joint Institute of.Nucl
ear
Research. The stacks were irradiated practically simultaneously..
in a 9 BeV proton beam, in a direction perpendicular to.the emulm-
sion plane. Results obtained from tracks of electron-positron
pairs and delta rays in a stack of 600 ~L Ilford G-5 emulsion irra-
diated by 17-BeV pions in the CERN accelerator are also presented.
The ratio of the ionization on the plateau of the ionization curve
to the value at the minimum coincides for the different emulsions
within the limits of experimental error. The average value of this
ratio is 1.104 + 0.010. The observed ionization-momentum dependence
agrees with the curve calculated on the basis of the Ste rnheimer
equation (Phys. Rev. v. 88, 851, 1952; 89, 1148, 1953; 91, 256, %
