During period 1942-1946 authors were stationed on Mount Alagez, at an altitude of
3 250 m above sea level. Discerned cowtic particles very different from mestrtrons
and protons. Series of tests revealed dats. which showed that these particles to be
ionized gases, two to three times greater than either protons or mesotrons. Mass of
this intermediate particle is 250 to 2,000 mo. They are either positive or negative.

Authors reported in previous artiole that, as a result of magnetic analysis of
composttion of cosmic radiation at, an altitude of 3,250 meters, new particles discovered
which have amass greater than the mass of the mesotron. Also presented data showidg-
that, in cosmic radiation, there are particleB with a positive and negative sign, the
mass of which exceeds that of the protron. This new group of elementry particles
named varitrons. Preser;t article!-presents results.-of spectrum analysis of these now

The authors at first discuss the advantages offered by heavy-water reactors
for atomic power stations, namely the high neutron multiplication fantor,
because neutron capture in D 20 is low, so that natural uranium can be burned
and a high burn-up of U 235 iE attained.
The high reactivity allows a large surface of the fuel element. Because of
the high costs of D 0 quantities used should be as small as possible. In the
first construction D20 was uEed as moderator and as coolant. This proved to be
insufficient,
As at a given maximum temperature of the fuel elements heat transfer increases
at a low coolant temperature whereas the thermal efficiency of the power pro-
duction is increased, the revult is an optimum which at 230 0 C results in only
2,5 atm wet steam excess prefisure for aluminium fuel cans and 10'. efficiency
for the vapor power works. AEi this is considered to be inadequate from an
economic point of view, a second construction was provided with gas cooling
at Tmax = 4000 C and 29 atm steam excess pressure and with aluminium alloys
which would theoret-.".cally PeMit 4700 C and 90 atm excess pressure.

ABSTRACT In connection .Yi",h the cheeking of the law of conservation of pari-
ty,the authors CUrried out experiments concerning the discovery of
a longitudinal polarization of electrons on the occasion of 8-decay.
For the determintttion of this polarization the effect of the azi-
muthal asymnetry was used; it occurs on the occasion of the simple
scattering of electrons polarized vertical to the direction of mo-
tions through a large angle on a thin foil of a heavy element.The
longitudinally polarized 8-electrons were sent through an electric
field crossed by a magnetic field.In these crossed fields a trans-
versal polarization occurred in the electrons. The reasons why this
method should be favored are given.The numerical parameters of the
ineqsuring device used here are given.tleasurements were carried out
in the energy domains of 300 keV.1t an electric field strength of
18,3 keV/cLi and a magnetio field strt:ngth of 11"- 79 Oe the spins
were turned by the angle of 9-500.The expected amount of the azi-
muthal asrmmetry can he determined from the data -iven in a table.
For the expected effect of azimuthal asymmetry in the plane which
Card 1/2 is vertical to the direction of spin the value bexp, - 27,7% is found.

The Polarization of Electrons on the Occasion of 5-i) a
Measuring resuli*,s are given in a further table. They shoxi 'that
there is no asynmetry in the plane of the turn of the spin by 0
1800. An asymnetry is ob*rved in the plane go-2700,where the
sien. changes if the direction of the field is reversed.The sign
of asymmetry is determined by the fact that on the occasion of 2-
decay the electrons are emitted vith a spin directed against the
motion of the electrons.For the (le6ree of the polarization of the
electrons on the occasion of 2-decay the expression 9(17)4:t2,6)/
/27,7 = (0,63;t0,09)B is found. The experiments concerning the mea-
suring of the polarization of electrons in the case of B-decay tend
to show that parity is not conserved in the case of weak interac-
tion and that the theory of the tvo-component neutrino suggested by
Landau agrres with the experiment.

ABSTRACTs The authors reported already in a short communication
(referonc,) 1) on experiments in which a longitudinal
polarizat 'ion of the A-electrono was found. This work
now descrAbes more exactly these experimento rnd control
measurements. The experimental arrangement consisted of
a device l'or measuring the turning of the spin and of a
device for the mousurement of the intensity of the
electrons, which were scattered through a wide angle, at
various azim-athal angles between 0 and )600. The
apparatus fo:~ the turAing of the spin consisted of an
oblong electi-ic capacitor which was in a meta.1 vacuum
tube. Then the authors shortly report on the accurtcy

field. The source of the P-electron3 4as laid upon
a 1OA4thick aluminium support as an even spot with
a diameter of 1 cm. The source consisted of segregations
from fraction solutions (oskoloclinyy rastvor) of
go 89
Sr with an admixture of Sr . The spectrum of.-the
electron energies of such a source is plotted in a
diagram. The thickness of the source plays an essential
role in such measurements. That part of the device
in which -*,here were the scatterer of the electrons and
the countors was separated from the capacitor by a thin
colloidal film. For the computution of the expected effect
of the azimuthal asymmetry the angle of rotation of the
electron spin in crossed fields and the dependence of the
azimuthal asymmetry on the scattering angle and on the
energy of the polarized electrons m-ist be known. A quite
complicated term for sin ~o is obtained, where(p means
the angle a)f rotation of the spin. The amount of sin y
depends to quite a degrce on the energy of the electron
and this e.;peci4,11-y in the ca--.c of high energies- 3 tables

details are discussed. An asymmetry in the direction

is (14,5 1 6t5)~4. In the direction 90 -2700 the
asymmetry is (42,8 -f 4,B)A. The data obtained on the
polarization need a correction because of the multiple
scattering at the scattering foils. The degree of

ABSTRACT: In an earlier paper (Ref 1) the ai;thors showed that the lorigi-
tudinal electron polarization in P-decay acts of heavy nuclei
(which corresponds to transitions forbidden in the first order,
i.e. the so-callod Coulomb (Kulon) transitions (,d J j 2) and
the unical trans~.'tions (-d J - 2, ja)) is equal to v/c with
% accuracy and in Independent of electron energy. However,
in one cese (RaE) an anomaly in the shape of the P-Spe$trum
is' observed in spito of the Coulomb transition (1- _* 0
By employing a method already described (Ref 1) the authors
determined the longitudinal electron polarization at the
mediun energies E - 125 and 3Q10 keV. The Ra(D+E)-source 2

The Polarization of the Elecllron of PaE and Time-Parity
of the electrons amounted to 0.733 � 0.06 and 0.725 + 0.06
(mean value 0.73 + 0-04). B. B. Geslikenbeyn, S. A. lit-3mirovskaya
and A. P. Rudik calculated the longitudinal electron polariz-a-
tion of RaE for the VA- and ST-variants in consideration of
the non-conservation of spatial parity, but with conservation
of parity with r,~spact to time (but also for the case of
the non-conserva"lion of time-parity). The disturbance of time-
parity is less than 7-5'5o. This is the most accurate estimate
of the conservation of parity vith respect to time that has
hitherto been made. Possibilities of a further improvement of
this estimation are pointed out in short. There are 8 references,
2 of which are Soviet.

ABSTRACT: In the present paper the authors publish the results obtained by
the investigation of particles which were produced by high--
energy nucleons of cosmic radiation dt an altitude of 3200 m
above sea level. Investigations were carried out on MountAragats
in Armenia. Th-a experimental device used is shown by figure
in form of 2 ajactions which are vertical to each other. The
device, in principle, consists of a mass spectrometer (6850 Oe),
an additional hodoscope arrangement, and a five-layer thin-
walled proport!.onality counter. Two series of measurements were
carried out: with generators ( 10 and 25 cm lead) and control
tests "without generators" (0.3 - 2 cm lead total substance
thickness). Mea.suring results can be divided into 2 groups:

b) particles of stars produced by charged particles and single

range method. Figures la,b show the results of momentum- and
ionization measuremonts of secondary particles under 25 cm of
lead of groupa a) and b). Sufficient data could be obtained fror
the experimental material concerning secondary protons and
partly also concerning deuterons. In 2 series of measurements
carried out iathe momentum range of 400-900 Idev/0 35 deuterons
were observed, 10 of which had been produced by protons. Thus,
cosmic radiation in an altitude of 3250 m had 3.5 times as many
neutrons as prDtons. The momentum spectrum of deuterons in the

ABSTRACT: The nonconservation of spatial parity in the case of weak inter-

polarization. The direction of this muon polarization has hither-
to not been experimentally determined. The authors suggest a
theoretically justified method of measuring the direction and
the amount of polarization, and investigate the possibility of
carrying out such experiments with accelerators and in cosmic
radiation. This is done on the basis of a formula given by
Berestetskiy for the scattering cross section of polarized
muona on polarized electrons. This formula shows that the croon
section is indapendent on polarization and that, if the energy

the case with a ((-shower having a certain number of particles,
which is caus,?d by muons in magnetized iron. According to the

Artsimovich together vf--th 1.'V. Kurchatov and others, worked in
the field of neutron physics and investigated the laws of
conservation in olsotron-posit.rcii annihilation and in the
Compton effoot. ile further investigated the interaction of fast
electrons with matter, theoretical and experimental problems of
electron optics, especially of the chromatic aterration of
electron-optical systemsi Il, 1945 he carried out a theoretical

of isotope se.paration and the aberrationless focusing of
wide-angle io-a beams in axially symmetric wagnetic fields.
Together with a group of physicists under his supervision, he
investigated high-intensity pulse discharges in rarefied
deuterium (plasma heated to several millions of degrees); in 1952
this group of*research scientists discovered a new phenomenon:
this plasma wELS found to be,a source of neutrons and hard X-ray
radi~ation. Since that-time, Artsimovic'h has been busy
investiCating thermonuclear reactions. He attended the second-
Geneva Confereince for the Peacdful Uses of Atomic Energy in 1958.
He. taught at the Leningradskiy politekhnicheskiy institut,
(Leningrad Polytechnic Institute), at L 'cninZrad University, at

TEXT: The emission and resonance absorption of gamma ray-i without loss of
energy during nuclear recoil, dincovered by M6ssbauer, permits an immediate
observatiou of the Zeeman splitting of excited nuclear levels and measure-
ment of their magnetic momerls. The gamma transition in Sn119m (23.8 kev;
lifetime, 2.67*10-8 Sao; lerel width, 2.5010-8 ev) was selected for the ob- V
servation of the Zeeman effect, and some results pertaining thJreto are
reported in this "Letter to the Editor". It was necessary to use a sample
enriched to 96% J~L.,Sn I j BJn vhich the fraction of Sn 112 was less than
0-05%, as the In"-' produoed from SnI12 is a strong scurce of -24-kev

TEXT: The muon chirality was measured by the, authors -.)f the present
"Letter to the Editcr" by a a.ethod described in Ref.l. The method is
based on the measurement of the scattering cross sez~tions of polarized
muons from polarized electrc,ns, This cross sestion dependa on the mutual
orientation-of the spine of the colliding parti~_les. An independent mea-
surement of the number of 6 showers was made., the showers being released
by cosmic muons in magnetized iron and consisting of two or more par-
ticles. The experimental arrangement is shown in a Fig. and described in
the text. About 500 muons psas through the apparatus every minute, one or
two of these produce showers with m2O. Up to now 116;000 showers with
m2t3 have been reeorded. The energies of the shower-producing muons were

TEXT: The authors measured the polarization of ,~u198 electrons by means
of an apparatus resembling the one described in Ref. 4, but improved in
order to work with a beta source exhibiting a strong gamma background. V1
The measurements were made in the ranges of 145 kev and 390 kev. Equal
Au198 and Tm170 samples seived as sources. The corrections for the two
samples were mutuall compensating. At 145 kev, the lonGitudinal
polarization of A09~ beta electrons was PAu/PTm = O-8OtO.O5 relative to
Tm170, and was thus smaller than -v/c. Comparable val7.-s were obtainei by
P. Ye. Spivak and L. A. Mikaelyan (Ref- 7). At 390 kev, PAu/PTm
= 1-07�0-08- A paper by B. V. Geshkenbeyn and A. P. Rudik is referred to
as containing an explanaTlTn of the de-y-15tion from -v/c at low encrGies.
