ABSTRACT: The experimental distribution of the tramverw components Pf the
momenta of secondary particles Is compared with the predictions of
the hydrodynamic theory of the multiple formation of particles. It
was shown that the conclusions of the onedimensional variety of
this theory agree well with experimental data if a final tempera-
ture of TE M02/k (m = mass of the Tt -meson) is assumed. This
agreement makes it possible to make statements concerning the
character of W - 7C -interaction. (With I Illustration and

ABSTRACT: Lately, the fact that on the occasion of the collision.of two
high-energy particles always several mesons are produced, has
been more and more experimentally confirmed. A logical inter-,
pretation of the phenomenon is lacking. The various experiments
to set up a theory of nultiple production of particles are based,
upon more or less good fundamental conditions, the accuraf-ly of
which can be confirmed only theoretically.
A theory promising a special. success was proposed by FERMI, who,
includes the statistical course in his theory. In the present
paper this theory is derived, explained, and extended.
The following individual problems are solved theoretically:
".
1) Interaction between particles. Selection of the "volume
.
2) Isotopic spin, equality of particles, distribution of the
charge states.
3) The phase-"volume"

_j,ABSTPACT: A study of high energy muons, using the horizontal flux zenith angles zBoo
of cosmic rays at sealevel was made and an ionization calorimeter developed for this
purpose is described. Such a study is feasible because the horizontal f-luY at large
zenith angles 0 consist almost exclusively of muons and the intensity of muons for
energies >1011 ev increases with 0. The apparatus uses muon flux to study high ener-
gy muon interactions with matter and measures the characteristics of the horizontal,
muon flux to deterviine the angular and energy distributions. The ionization calori-
meter enables one to study both of these areas by observing the sho'.'--rs produced by
the 7nuons due primarily to bremsstrahlung and nuclear interactions. It detects.muon3

at sea level on an Ionization calorimeter consisting of six rows of Ar-filled
ionization chambers, 25 In each row, with an iron Interlayer between the chom

ABSTRACT: Investigation of primary cosmic.radiation has been initiated,
using artificial satellites and cosmic rockets, resulting in the dia7.
covery of cosmic and galactic x-rays. A natural mechanism consisting,
of the appearance of a large number of electrons with energies from
0.01-10 Mev is assumed in the form of 6-electron formation by fast..-,.
cosmic-ray protons. Formulas are developed,for-the;probability.of
67electron formation by photons and for the differential spectrum of~
primary protons. The probability of 6-electron formation is great
.compared with the formation of electrons at if -0, )j _e decomposition.,

small compared with that observed, it is nearer to the real flux than
the fluxes obtained by other mechanical models. The total energy of
cosmic radiation, as well as of radiative sources and the Galaxy is
greater than that found by the authors. Under such conditione, it.is
difficult to consider supernovae as the basic source of cosmic rays,

ABSTRACT: An analysis has been made of the channels for dissipation of the
energy of the nuclear.and electron components of cosmic rays in the
.Gal!~pg and Metagalaxy. This paper considers the specific forms of trans-
NI --fer of energy expendedon ionization. In thelast analysis the ioniza-
energy consists of the energy of slow electrons 10-100 eV).
Ifost (-75%) of the energy,of slow electrons is 6xpended on the excita-
:?gen (for the most part the transition fis-2p
..tion of interstellar hydr4 -79
'uhich then is.-luminescent). The author formulates the problem of the
subeecraent fate.of the ultraviolet. Some part of theenergy is expended
.:on the.formation.of decelerating photons.by slow secondary electrons'.
relatively greater -part of the energy in this intermediate mechanism
is expended on the formation of X-rays. The author expresses 'to

The extent 0* his overestimation depends on the law of fluctuations in the
number of particles and angles (at a given energy), which at present can be
.estimated only in a very approximate manner. From an analysis of experimental
data on shower energy determined fromthe angular distribution of secondary
particles and measured directly,,an attempt is made to determine thedispersion
of distribution that characterizes the elementary act.
The error in the determination of the energy of showers produced on heavy,
nuclei is also considered. This error arises due to indeterminacy in theJength
of the nuclear tube withwhich the collision occurs.

ABSTRACT: The authors first shortly discuss the papers hitherto published
on this subject.(Refs 1-5)- In the present paper the passage
of muons of high as,wellas of low energy.through,.matier.is
investigated, in which connection all,known forms of muon-,
interaction and also the fluctuations of.energy losses are
taken into account. The interaction processes 'of relativistic:.
muons are divided into such as lead to continuous energy
losses and into such as lead to rare losses in large portions.
Among the processes of the first kind, ionization losses
(including Cherenkov radiation), and among those of the
second kind bremsstrahlung, the direct formation of electron-
positron pairs,as well as collisions leading to the fcrmation
M nuclear-active particles~are classed. In the approximation

ABSTRACT: When investigating the expansi on curve of.showermuons of

covered a distinct salient pointin this curve in the case
of short dista IncPs (N 1-2m) between the counter systems'with
which measurements,were carried out. The authors gave an':-
explanation for the occurrence of this salient point, which
is discussed in short by the present paper. It was,,however,,~
found that further investigations.,are necessary in order.
to obtain a satisfactory explanation, e,spe.cially:with respect
to the multiple production of muons in matter. In~the~present
"Letter to the Editor" the author makes a contribution
to the discussion of this problem. Local showers in great,
depths maybe caused'l) by.muon pairs produced by,photons,

TEXT: The authors describe a method of measuring the effective rate of H2
oxidation, 02 reduction, and "combustion" of oxyhydrogen gas on a platinum
electrode, based on gas consumption. A confrontation is made with data
found earlier by polarography (Ref. 11: K. I. Rozentall, V. I. Veselovskiy,
Zh. fiz. khimii, 11, 1555, 1732, 1957). Fig. 1 shows the experimental
arrangement. The electrode to be tested-is placed in the central part A,
and the auxiliary platinum electrode B is situated in.the lateral
ramifications along with the reference electrode C (Pd sheet saturated with
H2).. The electrode to be tested consisted of a platinum net wrapped around
a glass tube which was caused to rotate at 700 rpm by a magnetic field. A
