TEXT; The physical and mechanical properties of arctic snow
were dater-
mined at the drifting polar station Q-10 (SP-10) during
April - 114ay 1962.,
Using an ultrasound pulse method, the velocities of
longitudinal and trans-
verse waves were determined from the snow cover and from
aampli3 of differ-
ent densities. Measurements were carried out in horizontal
--ind vertical
directions both in the snow cover and in samples. Results:
Youngla
modulus and the velocities of the waves determined from the
samples in-
crease monotonically with density and show no great
difference whether the
snow is investigated in horizontal or in vertical direction.
The velocities
determined in the snow cover in vertical direction are
greater by a factor
of 2 than those determined in horizontal direction. These
results can be
explained by the effects of recrystallization. There are 1
figure and
1 table.

ABSTRACT In the postwar years the investigation of cosmic
radiation became
more and more important. The discovery of the so-called elementary
particles, the observation of their decay and their mutual
transfor-
mation exercised a great influence on the conception of matter.
The
author thinks that the problem of elementary particles belongs to
the most important of today's physics. In spite of that some
scien-
tists recently advocated the opinion that the great importance of
cosmic radiation was already part of the past. The author believes
that this opinion is false, since elementary particles exist in
the
cosmic radiation which possess gigantic energies (up to 1018 eV
and
more). The Union Institte of Nuclear Research in Dubno near Moscow
put a synchrophasotron into operation; the normal energies of ele-
mentary particles exceed this most efficient accelerator million-
-fold. It is known that now and then a sudden, short increase in
Card 1/2 the intensity of cosmic radiation takes place ( the last
one was

Important Research Works of Topical Interest. On the Importance
of
the Investigation of Cosmic Radiation
observed on Feb, 23, 1956). In the course of the geophysival year
unthought-of achievements will be attained. it is clear that the
investieat-ion of cosmic radiation has to be further intensified
in
the U.S.S.R. The experimental work has to be closely connected
with
the theoretical one. Only by successful development of theory it
will be possible to find a way from the interactions to the
nature
of the colliding particles.

Physics Institute,
Acaleny of Sciences, U.S.3.R.) with the aid of an arrangement
that permits
of a comprehensive study of an Individual act of nucear
interaction.
2. The arrangement consisted of two cloud chambers with a
target of. a light
substance (LIE In the main series of experiments) interposed
between then. In
this target the interactions under study were generated. The
bottom cloud
chamber was placed in a 6500-oersted magnatic field, which
enabled us to
measure directly the pulses of secondary particles. Under the
chambers was a
special device ("ionization cilorimeter") made up of 120
ionization chambers
,,rranged in 8 trays with filters between them. This device
made it possible
(from the total amount of energy generated) to determine the
energy of the
particle that produced the interaction being studied.

ABSTRACT:
The author
recapitulates the principal stages of in-

S.N.
Vernov's sounding balloons of the thirties Which

reached
altitudes of 30 to 35 Im, S.N. Vernov's and

A.Ye. Chudakov's
investigations of cosmic rays by

means of rockets and, along
with N,L. Grigorov and

Yu.1. Logachev, later investigations
using artific-

ial earth satellites. The results of these
latter

investigations have largely been placed at the dis-

posal
of the joint committee of the IGY and com-

prise summary
radiation phenomena as well as those

of individual cosmic ray
particles. Special research

was devoted to the study of the
heaviest multi-charged

nuclei in the primary cosmic radiation
using the Che-
Card 1/2

with numbers, energy-output and possible origin of
diverse cosmic radiation particles and their distrib-

were given to the evaluation committee of the IGY.

TEXTt The authors report on investigations of the inner field of
the
nucleon, according to which it can be subdivided into a central
and a
peripheral region. Accelerators and cosmic rays are mentioned as
sources
of high-energy nucleons. The accelerator of the Ob"yedinennyy
institut

Dubna
enables a proton acceleration to 10 Bev. The Pamirskaya stantsiya
Fizicheakago instituta im. P. N. Lebedeva Akademii nauk SSSR
(Pamir
Station of the Institute of Physics imeni P. N, Lebedgy of the
Academy
of Sciences USSR) has obtained new data on nucleon-nucleon
interactions.
Since it is rather difficult to determine the energy of the
primary
particles by the photoemulsion method, a new method was
developed,

which is based on the measurement of the total ionization.
Such an
"ionization calorimeter" was designed at the Pamir Station
with the co-
operation of N. L. Grierov and S scientists of
Moskovskiy universitet (Moscow UnivieEL1.11), the author,
and other co-
workers. It consists of a Wilson cloud chamber (volume of
70 1) which
is placed in a 6000-oe magnetic field. Lithium hydride
serves as target.
There are eight rows (120 pieces) of ionization chambers,
serving as
"calorimeters", below the Wilson cloud chamber,, The
energy of the primary
particles could be measured with an accuracy of about 30.
A new apparatus
with a greater number of ionization chambers is to improve
accuracy. The
showers investigated so far can be subdivided into three

inelasticity coefficients K of both nucleons are

TEXT: Bergey Nikolayevich Vernov celebrated his 50th
birthday on
July 10, 1960. The beginning of his scientific activity
coincided with
the beginning of an intensive research on cosmic rays
(1931-1932). By
his first studies he built the foundation for the
present-day methods
of investigating cosmic rays inside and outside of the
stratosphere by
means of radio signals emitted by automatic devices. From
the start,
Vernov worked in close contact with Academician D. V.
Skobelltayn. In
1939, he completed a series of studies on cosmic rays in the
strato-
sphere, measured at various latitudes. Stratospheric
measurements made
by Vernov from 1946 to 1949 yielded particularly detailed
information
on the nature of primary radiation. Basing on rules found by
experiments

to govern the absorption of the primary components in the
atmosphere,
Vernov reached an important conclusion concerning a strong
interaction
of the primary particles of cosmic radiation with matter. In
1949,
S. N. Vernov headed an expedition of Soviet physicists to
the equatorial
latitudes in the Indian Ocean. Stratospheric investigations
made in the
course of that expedition yielded convincing evidence of the
existence
of the disputed, so-called east-west asymmetry and of the
positive
charge of particles of cosmic radiation. For his research of
cosmic ra-
diation in the stratosphere, Vernov was distinguished with
the Stalin
Prize of let Class in 1949. From 1947 to 1949, Vernov
organized compre-
hensive studies of the interaction of high-energy protons
with matter in
the stratosphere. Collisions of protons with atomic nuclei
were found to
give rise to an electron-photon component of cosmic
radiation. This al-
lowed tho assumption that rapidly decaying mesons giving
rise to the
formation of photons and electrons are produced in the
course of such
processes. This hypothesis was confirmed by the discovery of
no-mesons.
In 1949 and 19519 Vernov and collaborators obtained
experimental data
confirming the presence of nuclear cascade processes in
1010-ev primary
cosmic particles. Vernov supervised comprehensive research
work on the

interaction of cosmic rays with matter and obtained an
insight into the
mechanism of the formation of secondary cosmic rays in the
atmosphere.
It became thus possibl.3 to describe this process
quantitatively. On
Vernov's initiative, elementary processes of the interaction
of
1011 - 1013 ev particles with atomic nuclei are being studied
from a
atratoplane. Under his supervision, a first-class laboratory
was eatab-
lished at Moskovskiy gosudarstvennyy universitet (Moscow
State Universi-
ty) to serve for research work on interaction of
ultrahigh-energy par-
ticles (1014 - 1o16 ev) with matter. The USSR network of
stations for
the permanent recording of cosmic rays was established with
his partioi-
pation, and is now operating under the IGY program. In
acknowledgment
of his scientific achievements, Vernov was elected
Corresponding Member
of the Akademiya nauk SSSR (Academy of Sciences USSR) in
1953. He was
awarded the Lenin Prize in 1960 for his discovery and
research of the
outer radiation belt of the earth. S. N. Vernov is the head
of the
NIIYaF MGU (scientific Research Institute of Nuclear Physics
of Moscow
State Univeraitg , and runs the special section of the
fizicheskiy fakult-
tet MGU (Department of Physics at the MGU). There are i
figure and
37 Soviet references.

TEXT; Experimental data on NN-interactions, obtained by a team of
the
Laboratory of Cosmic Rays of the Physics Institute AS USSR at its
Pamir
station (3860 m), are discussed. Photographs of such interactions
revealed
the presence of showers with asymmetric particle emission in the
c.m.s.
Of 48 showers, 18 showed marked asymmetry. The data obtained with
the
arrangement shown in Fig. 1 were evaluated by conventional
statistical
methods and also by the Monte-Carlo method. It is shown that the
probabil-
ity of asymmetric showers being caused by fluctuations in the meson
angular,
distribution does not exceed some per cent. The fact that the shower
symmetry depends on the inelasticity ratio of the interacting
nucleons

allows NN-interactions to be divided into three classes: (1)
symmetric
showers with small and approximately equal coefficients of
inelasticilty
Klab and Kmirror ; (2) asymmetric showers with very different
coefficients;
and (3) symmetric showers with both coefficients being large (K>
0-4)- It
is explicitely shown that the experimental results can be
interpreted with
the aid of a simple structural model of interactions for the above
classest
(1) peripheral--- peripheral interactions;.(2) peripheral - central
inter-
actions; and (3) central - central interactions. In collisions of
class
(2), for exampl.e, the periphery of one nucleon is assumed to
interact with
the center of the other. The data obtained also show that an excited
meson
cloud appears in-v1OO Bev NN-collisions, which does not contain the
colliding nucleons. In general, this cloud moves slowly relative to
the
c.m.s., and decomposes isotropically when its temperature reaches a
value
Tr,*L.. Thelbpectrum" of the radiation or energy distribution of the'
mesons is comparable with that of an absolutely black body. There are
12 figures.
