TEM The present paper gives the results of an investigation of neutron-
deficient osmium isotopes on the synchrocyclotron of OIT&I (Joint Institute
of Nuclear Research). The oemium, isotopes were produced by bombarding
,r-0.2 g of gold with 660-Nev protone for I ' 2 hours. The purity of the
separated elements was radiochemically checked. A 100-channel scintillation
gamma spectrometer and A- and C-counters were used to analyze the beta and
gamma emission of the nuclear reaction products. Fig. 1 shows the gamma
spectrum of the osmium isotopes obtained. The authors identified
08182, Os 183 , 091834, and Os185 which had a half-life of at least 10 hours.
In addition, the spectrum showed an intense line, Er ' 230 key, which bad

initial orbit.
It is known that the content of natural radioactive elements M Th, K40
in terrestrial rocks decreases from acidic to basic to ultrabasic rocks and
that the decrease covers a range of several orders of magnitude. Therefore,
it was expected that it would be possible to determine the type of rocks
present in the lunar surface from the relative content of U, Th, and K
established from the the rray spectrum. In conducting the experiments, the
fact that the level of Y-radiation from natural radioactive elements can.
be lower than the level of Y-radiation produced during the interaction of
primary cosmic particles -(primarily protons) with the lunar surface was taken-
into account by analyzing the characteristic ),,-rays emitted during the
interaction.

ground from charged particles, the NaI(Tl) crystal was enclosed in a container
of a thin plastic scintillator. The pulses generated by charged particles were
registered by the Nal(TI) crystal and the plastic scintillator and were then
separated from the pulses generated by 'Y-rays which went practically
unregistered by the plastic scintillator.
The scintillation spectrometer recorded ~Y-ray spectra in the energy
ranges between 0. 3-3.1 and 0.15-1. 5 Mev. The switching of energy ranges
was performed by ground command. The detector and the analyzer of the
spectrometer wom Imatod in a hermetically sealed compartment under a shell

Six Y-ray spectra in the energy range 0. 3-3,1 Mev were obtained during
the first month of operation of Luna 10. In addition, the integrated intensity
ot. -r-radiation in the same energy range was obtained at approximately
points. The measurements were conducted over relatively wide surface
-areas covering the continents and the seas on both the light and the dark

and the absence of -t-rays with energies greater than 2. 62 Mev. This shows
that most Y-radiation from the lunar surface is not associated with the

cosmic rays with the lunar substance and the decay of cosmogenic isotopes.

Since the lunar surface is exposed to constant interaction with cosmic
i rays, all of the cosmogenic radioisotopes should be in radioactive equilibrium.
Therefore, both long-lived and short-lived radioisotopes should be radio-
active, and their content should be proportional to the effective cross sec-
tion for their production. Calculations show thatithe main contribution to
Y-ray emission is made by the decay of the folloN~ing cosmogenic isotopes:
0"(TI/2 = 72 sec, E = 2.31 Mev) 0 19 (T, 12 = 27 sec, E - 1. 37 Mev),

Na2 (TI/2. = 15 hr, E Y = 1. 37 Mev and 2. 76 Mev). These raJioisotopes are
formed with a considerable yield in nuclear reactions involving the same
rock-f orming elements: Mg, Al, and Si.
The peak at 0. 51 Mev, which is especially p ronounced in the lunar
Y -ray spectra measured in the energy range 0. 151r'-1. 5 Mev, is produced
by Y-radiation emitted during annihilation.
Analysis of the results shows that the Y-radiation intensity corrected
i for the difference in height is practically constanf above the different regions
of the lunar surface (intensities did not differ by m ore than 4076). This can
pr obabl y be attributed to the fact that the main source of Y-rays is cosmic
radiation. A preliminary analysis shows that the total dose rate of

assumption follows from the fact that the spaceship and its cumponents were
made of light alloys of Si, Al, and Mg with very I,ittle Fe, i. e., the dominant
elements in the composition of rocks. Curve 3 in Fig. 2, obtained by sub-
tracting curve 2 from curve 1, shows the-y-ray spectrum produced by'the
decay of natural radioactive elements. Fig. 2 shows that 9010 of the intensity
of gamma radiation emitted by lunar rocks is produced by radioactivity
induced by cosmic rays and no more than 1011,16 by decay of K, Th, wid U.
Prior to the flight the Y-spectrometer aboa!rd the spaceship was pre-
calibrated using samples with a measured amount of K, Th, and U and also
with rock samples containing different amounts of these elements. This
procedure made it possible to calculate the Y-ray spectra, which should be
obtained by the orbiting spaceship, emitted by rocks with different amounts
of natural radioactive elements (it was assumed that the radiation produced
by cosmic rays is absent). Fig. 3 shows such spectra which would be
obtained at a height of 350 km with the background subtracted from the
,spectrum. The hatched areas correspond to range of emcentrations of
radioactive elements for given types of rock, The average values of con-
centrations of K, Th, and U were taken from a p#per by A. P. Vinogradov
(Geokhimiya, no.. 7, 1962).

Comparison of the lunar -(-ray specitra
with a known content of K, Th, and U shows that at least in the.regions of

the lunar surface,' or at a depth not exceeding 27cm, containing the same
amount of K, Th, and U as do the acidic terresttial rocks, such. as gran-
ites. The intensity of y-radiation due to natural radioactivity (Fig. 2,
curve 3) tends to indicate the presence of basic!rocks such as bas'alts.
However, at the pres6nt time It is impossible to exclude the posBibility that
the concentration of natural radooctive elements w~as estimated a bit too high.
It is interesting to note that tektites, which have almost the same composi-
tion and amounts of U, Th, and K as acidic rocks, cannot be of lunar origin.

ABSTRACT: In a brief survey of the literature, the authors discuss various problems
which have recently arisen with the analysis of isotopes formed by cosmic rays in
meteorites and other objects from outer space. The sources considered in this pap-
er am di!.,ided into two categories: astrophysical and nuclear. The first deals
with problems in the origin and evolution of me,teorites and cosmic rays, while the
second is concerned with a study of the structure of atomic nuclei and the mechanism
of nuclear reactions under the influence of high energy particles. Tables are giv-
en showing the radioactivity of cosmogonic isotopes as well as the concentration of

stable isotopes in iron and stony meteorites. The cosmic age of meteorites is
termined from the ratio of the concentration of cosmogonic stablz nuclei to their
rate of formation at the present time. It is found that most of the stony meteo-
rites have a cosmic age of .106_6.107 years. The: cosmic age of iron meteorites is
found to be 1-7-108 years: All meteorites whose .ages have been i,.ieasured are young-
er than the geological age of the. earth, which is %,4.5-10'3 years. ItJs concluded
that all meteorites were produced in one or two gigantic catastrophies. Curves are
given showing the accumulation of cosmogcnic isotopes in a meteorite. These curves.

Short-lived isotopes quickly reach equilibritza and the curve for their radioactivi-
ty with respect to time is practically a repetit,ion of that for the intensity of
cosmic rays. After the meteorite falls to the earth, the radioactivity of the cor-
responding isotopes falls exponentially. The nLimber'of stable isotopes continues
to increase even after the fall. The integral spectrum of protons and alpha parti-

for various nuclear phenomena caused by high energy particles are discussecl. Ex-
perimental data indicate that casmogonic isotopes are formed in diffevent meteorites
under identical conditions, However, the differences in the meteorites with respect

ABSTRACT: The effect of temperature and deformation velocity on the formation of
substructure in steel was studied in the pro(MS4 of plastic deformation at high
temperatures. The samples consisted of Cr-Mn a6tenite steel (0-37% C) alloyed
with W and Mo. Their substructure (revealed byietching) was studied microscop-
ically and the structure patterns were photogrs~hd- It was established that a
plastic deformation cf the metal at 1000-1200C iand at deformation velocity 0-015-
0.0035 1/aeo caused the appearance of substruct~ure. The size of the substructure
elements increased with the increase in tempera ture and with the decrease in
deformation speed. The origin of the substnicture observed was explained by the
redistribution of dislocations in the process of deformation at high temperatures.

ABSTRACT: A study was made of the fir

chromium-nickel-manganese steel EI4811as a function of the conditions
of high temperature heat and mechanical treatment: temperature and
degree and rate of deformation. Samples vith dimensions 50 x 50 x
75 mm were heated to 120000, hold there for 1.5 hours, and deformed
at this temperature and at 1100 and 10000 after cooling In, the furnac

Deformation was done by, 25-30% u Gatlin In a press at a rate of
0.015, 0.0075, and 0.005 i/sec (the degree of deformation was evalu-
ated by the change In height of the sample). After deformation (with-
In 1-2 seconds), the samples were quenched in water. The test samples
were subjected to metallographic and x-ray structural analysis. Study
of the microstructure (illustrated in the article) shows that, as a
result of high temperature heat and mechanical treatment, there
appears a structure whoee elements depend substantially on temperature
and the rate and degree of plastic deformation. Treatment at 12000 at
a minimum deformation rate leads to formation of subgraina with an
average size.of 30-40 microns. A decrease In deforwation.tempera-
ture to 1100 decreases the size of the subgrains to 15-20 m1crons.
X-ray studies show that, In samples which have undergone conven-
tional annealing, the grains have a sufficiently clear character
with a small radial washing out, which probably Indicates a certain
elastic microdeformation of the lattice. For material subjected to
high temperature heat and mechanical treatment, the x-ray studies'
indicate the formation within the grains of large mutually unoriented
regions of the crystal lattice, that Is, fragments. The magnitude
of the plastic deformation has a complicated effect on the formation
of the thin crystalline structure. It small reductions, the frag-
mentation of the structure is observed mainly in regions near the

structure in a cross section of the order of 50 x 50 mm, and leads to an improvement

ABSTRACT: The present work deals with the preliminary results obtained
by studying 29 showers by the method of the emulsion chamber.
The emulsion chamber consisted of 100 layers of 10 cm diameter
and 450dothiokneas. This emulsion chamber was irradiated in
May 1955 for 7 hours at a height of 27 km. On the occasion of
the microscopic investigation of theme emulsions the explosion
showers were fixed with more than 5 relativistic traces which
are in a sufficiently narrow cone. Furthermore, the rays were
fixed with more than 3 rolativistic traces. On the occasion
of the examination of 26,5 om3 photoemulsion 27 explosion
showers and 29 rays were found. In the course of a further in-
vestigation of the rays through the emulsion chamber it was
found that two of them originated from stars. The remain-Ing
27 rays were found to be electron-photon showers. On the
occasion of the microscopic investigation of the explosion

case of ultrarelativistic shower particles. By assuming a
nualeon-nuoleon production mechanism of the shower we find
n. a kV otg ~_1/2' Some showers satisfy this relation and
can thus be assigned to nuclison-nualson interaction. However,
the angular distributions of the shower particles contradict
this conclusion, for a noticeable asymmetry of angular dis-
tribution was found. All showers produced by nucleons and
a-particles have a marked asymmetry with respect to the
angle 0 - x/2.

ABSTRACT: An emulsion cnamber of 7 x 4 x I cz consisting of 23
layers of' an HoK0- photo,

was irradiated with slow positive pions of the Gv1q.1

Institute for Nuclear Research) synchrocyclotron. The chamber
was mounted in a double maZ;netic screen in order to make
cure that the scattered manetic field of the synchrotron
did not lead tc a precession of the spin of the nyon. In
lookinO., throu--h the emul3ions after developing those cases
were selected where the whole myon track of the z -~g-decay

ABSTRACT: The authors of the present "Letter to the Editor", when iLvesti-
gating the asymmetry of the angular electron distribution of
x_j,g -4 e-decay, observed that in one case three relativistic
electrons depart from the stopping point of the p-meson (of.
figure). All three electrons have large inclination angles with
respect to the emulsion plane, and therefore exact measurement
of grain density was impossible; it was, however# near that for
relativistic particles (energy.'I Mev). The recorded part of the
electron path length: Lei M 455 ;L, L e2 - 562 p, L e3 - 455 P.
The muon range amounts to R. a 598 p in the case of an average
path length of the muon of the n 4p-decay in a R-NIKFI-emulsion

as a muon decay in electron + r with a transformation of the
quantum into electron + positron at the place of decay, because
in this case the direction of the departure of the particle
pairs would have had to be opposite to the observed direction
of flight of the decay electrons. The explanations p+-4 e+ +

If the results obtained by other authors are taken into accountj
a probability of 10-6 is obtained. This order of magnitude is

shapes of AMg6m alloy and their welds had low sensitivity to crack
and stress concentration. The 20% strain-hardened AMg6ff alloy pl 6te8
were found to be crack and stress-concentration sensitive. The Amg6N
alloy welds, however, had a low sensitivity to cracks and stress con

of high-strength AT&M alloy (tensile strength over 43 kg/m=2) wore
found to be stress-concentration and crack sensitive, The results of
these tests led to the conclusion that AMg6N (gtrain-hardens 4Ams6)

ABSTRAq9 The object of the work was to study the weldability in the fusion welding
of V96 illoy, and also to determ~.na whether the weldability of this anoy can be im-
pr6,_ie_d by changing the chomical composition of the base metal and filler wire. She;t

o.o6% 0-13% Zr, 0.29% Fe, and 0-13% Si were useein the experiments. In order to
decrease the tendency toward crystalliz4 on crack 11~he welding should be carried bu
with Al-Mg alloy fillers (of type ANLQI~'Ths content of the main alloying elements i
the base metal should be kept within the following limitsi 6.5-7.5% Zn; 2.7-3.5% Mg;
1.6-2.0% Cu; 0.15-0.22% Zr. However, even then the tendency of V96-typo alloys to
forn cracks during welding remains higher than in comnonly used alloys of the Al-Mg

TEXT: This paper was presented on October 19, 1961 at a meeting of
the Korisja 7.:atematyczno-Przyrodnicza PTPN (Mathematical and Scien-
tific Committee, PTPNT). The Cotton-YoiAton'magnetic birefringence
constants, C, of nitrobenzene, m-nitrotoluene, o-nitrotoluene, o~____
nitroanisol, 1,2,-dibromoethane and their solutions in carbon tetra-
chloride were measured at room temperature uaing light of X = 547
mp. All these liquids were purified by distillation and (except
Ccl4) by filtering through A120 3* The constants were deduced from
the pha8e'difference between the ordinary and extraordinary rays
