2 ha
resultant specinens were studied in a scanning and a transraission electron
nicroscope aund their brittle strength neasuriad a,", room tenpematura. The re-
sults indicate both top growth from the'Atapor pl=e an4 bottor. Mwth from
the idelt. In neither ca-se is the presence of an,axialscrev dislocation a
necessar-
y corAition for crystallization in whisker fori.n. The aiticle dis-
cusses possible

Translation: The follow-ing basic -requirements are formulated for ortaniz-
ing data blocks. 1) the necessity, for selecting an effectiie systeri of
coding no-_uative data; 2) the necessity for wUnimizing. the -volurne of re-
duadant date; 3) the necessity for optimizing the distribution of data blocks
among the stages of the raemary devices to minimize the ~juanl(-Aty of normative
data in the process of retrieval and alteration; 4) the possibility of re-
cording and conposing normatives of data blocks of any volumes (both from
punched tape and from punched caxds); 5) ;the possibilit~r of checking all
operations of organizing the data blocks en ma6met-ia tar'es; 6) the possi-
bility of correcting normnative data blocks recorded on ragnetic tape. The
~general principles of constructing data blocks, are defined in accordance
with these requixre=nts. A method. irp de.s,cribed for tramsir.erring normative

noted that in organizing data blocks of normtive inforinat
Acn, it is es-
pecially important to provide for timely introduction of all chenges which
arise in the process of improv C I
ing technology and prrdu tion technique. in
this regard, the following changes are possible in rormcitive data blocks:
correction of outdated requisites of record; insertion of a new record;
removal of an outdated record. It is concluded that effective organization
of normative information on magnetic tapes and insertion of changes appre-
ciably reduces expenditures of vork and timed. in utilizing automated produc-
tion management systems.

Translation: Investigations of processes of heating by means of laser
sources -with different wavelengths are,of considerableiimportance for
explaining mechanisms of energy transfer in.laser heating of a plasma.
This paper tells of the development of a.high-power light source for
heating experiments with emission on, .two wavelengths: the wavelength of
a neodymium laser (1.06 )jm) and ltr, second harmonic (0.53 pm). An ef-
ficiency of greater than 501a in convel-ting IX6-wn emis'sion io the second
hea"monic is achieved in a KDP crystal. The emission enera on the 0-53-5m
Vavelength is 10 j with a pulse duration of 1.0 ns. Part I, see R7,hFiz,

It is demonstrated that deformations continue to incmasc behind the leadin-

degree of ionization occurs several.nanoseconds after the beginning of the
motion of the "elementary volume" of the plasma. This.freezing process also
occurs for the remaining ions. The laminar structure of the jet which is ob-
served in photographs is explained-on this basis. The~energv;lost by the plasma

Abstract: Nickel-copper-chromium cast irons have an austenite structure at
room temperature. At below-zero temperatures, however, the austenite in these
cast irons turns to martensite, vAich is followed by volumetric changes, an
increase in hardness, a

the effect of chromium, nickel, manganese, and copper contenbs on austenite
stability. The study involved 20 melts pro 0. It is noted in conclusion, -that tht:! pro_hl(%m of thC-

"KL -2p Decay and the Possibility.of Existence of a Light Vec-
tor Meson"
Moscow Yadernaya Fizika, Vol 16 Aug 72, pp 376-383
Abstract: The authors discuss the hypothesis which holds that
the existence of a liaht vector meson X0 is responsible for
the failure of experiments set up to detect 1%'L,,4-, decay. The
analysis shows that existence of a X-meson with the properties
necessary for compensating the two-photon contribution to
Im F (KI -* 2 v) contradicts experiment. This and other diffi-
culties seem to rule out the existence of such a particle.
If the hypothetical X-meson does exist, it w6tild have to decay
into new light neutral particles or undergo interaction
both unlikely possibilities. The authors thank V. V. Barmin,
17. S. Demidov, A. G. Meshkovshy', N. N.~ Nikolayov and V. A. She-
banov for constructive criticism.

Abstract: This paper is in the~nature of a review of the vexatious
problem of the decay of the XT
meson. There has been a great deal
of contradictory experimental and.theoretical data concerning this
problem, and the authors review the experimenta1and theoretical
evidence thorouChly, questioning it as they Co. They que.-,tion the
reliability of the experimental findings -- some. of -Which have led
to the negative result that no decay wasc detected -- and apply
equally radical examination to the re-liability of tho various
theories. 1,
-fter this introductory discussion,,the authors examine
a mathematical exDression of the decay,..as found'from a hiZh-ly ac-
curate exreriment, and consider its conrequences. Then, to plot an
exact path through this confusion of doubtful facts and erratic
U
theory, they carefully analyze the ne~. interactiens of Imown par-
ticles arising from the decay, the new particles~and particularly
the new light particles that have been found, and the theory of
conservation as applied to the decay,in addition~to apparent vio-
lations of the theory. In discussing this last, the authors touch

Abstract- This paper deals with the combustion 5cheme of a model 2-component.
gunpowder mixture, consisting of finely divided potassiuia nitrate and charcoal.
it is found that the position of the concentration limits of the combustion of
a model gunpm-7der mixture is detennined by the temperatu're equality of the
combustion products within the zone of influence of the J.Pnition temperature
a
of the mixture, namely the temperature of the transition of pot, ssium nitrate
into nitrite (Tf 111,000 K). Increased pressure, increase.:; the combustion rate,
as does also an Increase of the initial gunpow(lar temperiature, An opinion is
given with regard to the heratofore uneyplained influenc(-,~of thc-~ addition of
sulfur upon the combustion rate of smoke powders. The combustion raLe is said
to increase due to the formation of.K2S.in~the combusLioa:products, instead of
K20,, thus releasing approximately A0% more~heat and,liberating. more oxygen for
oxidation of the charcoal. 5 figures, 18 references.

Belokrinitskiy, et al, Pis'ma v METF, 15~ No 4, 1972, p, 198) it was found
that in GeTe films under strong light pulece a growth of crystallites was
observed, accompanied by changes in the physical and optical characteristics
of the compound. Similar characteristics, including tlie transmission and
absorption spectra, were explored in thepresent paper for the compounds
listed above. The equipment used for the holographic recording is shown in
schprAtic form. Records of objects measuring 2X2 mmz to 15X15 mm2 were
made by illuminating them directly with neodymium and ruby lasers. Samples

Compounds by Laser Emission"
Leningrad, Zhurnal Telhniclieskoy Fiziki, Vol XLII, No 3, 1972, pp 670-672
Abstract: Mass-spectrometric studies of vapor composition were performed dur-
evaporation of single GaAs and Gall, crystals by ruby laser emission. The
qualitative composition of the vapor in both cases was similar (the Ga , ~s
and As ions for GaAs predominate, and the Ga+, P :P, for GaP) ; however,
2
the relative intensity distribution between them io nal: retained. The pre-
dominant composition of the. part of the vapor hot ionii:ed by the Ifiser emission
was established by using additional ionization of the vapor:by a high frequency
spark. The causes of the quantitative differences in the vapor during e-vapora-
tion of single GnAs and GaP crystals, by xuby lasar emissioa were discussed.
The results were co--,.q)ared with analogous rn~ults for therinal evancration. In
the case of additional ionization of the plasma, the A; As an(.' Ga. 11 ratios
found from the mass spectra approach stoichiometric. Thus, the devree of
ionization of Ga during evaporation by laser. eiiiission is appreciably hi~,Iier
than for thermal evaporation, and the part of the vapor ionized by the liglat

"Structural Studies of Graphitization of Tliin,Carbon Films Under the Influence
~6f-Powerful Light Pulses"
Moscow, Kristallografiya, Vol. 16, No. 2, 1971, pp 41S-419.
t1stract: Changes in near order structure upon graphitization of carbon films
under the influence of powerful light pulses are studied:. Amorphous carbon
films were irradiated with light pulses of various energies, the process of
graphitization being continued to various.stages. The intensities of scatter-
ing of electrons by the irradiated films were -measured, and tLe curves of t,;i--
radial distribution of atoms were calculated, :The near order parameters were
determined for various stages of graphitization. A probable kinetics is
suggested for the transition of amorphous carbon to gra hite upon irradiation
P
of the initial films with light pulses of very high enorgy. It is suggested
that a double C C bond is produced;betwben'some of thet ~atoips in addition
tolthe single. C C bond in the graphitiz.ed films.
