is concluded-that reactions differing only with regard to the charge of strange
pexticles-occur with identical intensity. The experimental cross section ratios
are -in, good agreement with Fermi-toodel. calculations for sone ewes, and 1.5
-times smaller in~others. The bulk of the LAMDA hyperons am emitted backNard
vithin a-154-IW cone in the pion-rAucleon center of mass syste m. The angulax
distributions depend only slimtly on the atrange-particle charge. About P% of
theIAMDA hyperons are scattered in the parent nucleus. Comparison of the data
oil t"-'ie neutral Kaon-Antikaon-pairs produced in freon and xenon indicates that the
neutral Kaons are scattered considerably less frequently in the nucleus. There

ABSTRACT: The production of negative and neutral pions in the inter-
action between negative pions and nuclei, with small momenEum trans-
fer to t1he recoil nucleus, was investigated in a xenon bubble chamber.
The greatest interest in these reactions lies in the process of pro-
ducing a neutral pion in a Coulomb field, for this reaction can yield
information on the interaction between pions and gamma rays. The se-

lection criteria and the measurement procedures and the data reduc-
procedure are described in detail. An upper,limit of 1.0 + 0.2
mb is estimated for the cross section for production of neutral
pions in the Coulomb field of the xenon nucleus. This estimate.does
not agree with results by others and possible reasons- for the dis--
crepancy are suggested. "The authors are grateful to Ye. V. Kuznet-

TEYIP., The asymmetr coefficients for the angular distribution of the
decay products of X_ hyperons were determined from 360 reliably
identified _/\_~-particles and from 70 cases (A or KO) imperfectly deter-
mined.* These particles were produced by negative 2.8 BeV/c pions on
xenon nuclei according to x +p --> KO+A. The relation aP 0.27 + 0.12
holds for the up - down aaymmetry with reapect to the plane of production
of the A-particles at momenta from 400 to 900 Mev/c in the coordinate
system of Fig. 2. a characterizes the degree of parity non-conservation

P averaged over the production angle. ThL? transverse polarization
depends on the momentum of the A-hyperon ih the laboratory system and
perhaps changes its sign at the momenta >900 Nlev/c. Owing-to this low
polarizability, heavy nuclei cannot be used as targets for the produc.tion
of polarized particles. Systematic errors, difficult to control (being
perhapq of the same order as the effect itself)l make it more difficult
to draw exact conclusions as to the amount of aP 2* This amount
characterizes the forward-backward asymmetry. For all A-particles
produced according to n +Xe -3~A+K+Xe'+nn, perhaps aP 3 - 0. The quantity

TITLE: A Possible Case of the Disintegration of a Neutral Cascade

PERIODICAL% Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1960,
Vol. 39, No. 1 (7), PP- 44-46
TEXT: During the irradiation of a two liter Xenon bubble chamber with
negative pions (momentum 3 Bev/c) in the ITEF AN SSSR (Institute of
Theoretical and Experimental Physics of the AS USSR) 20600 iTo-~tographs
were taken. In their evaluation one was found, represented in Fig. 1,
which is assumed to disintegrate according to the scheme DO -+ K+ + Tr.
Fig. 2 shows the geometrical scheme of this decay event. The chamber
worked without a magnetic field. Identification of the particles was
made only according to ionization and multiple scattering. The results
of measurement are compiled in a table. In the diagram the path ends are
denoted by letters, so that the particles (i.e. the tracks) are described
in each case by two letters, Point b lies in the primary pion beam. The

directions of motion of the particles are denoted by arrows. The mass of
particle "be",which is stopped in the chamber volumeg was determined to
be (490�190) Mev, which agrees with the mass of the K meson within the
ste-Aistical error limits. The momentum determination for the 'led" parti-
cles gave the value (180+54) Mev/c, which corresponds to a KU 2 or K/J'2
decay. Further considerations showed that the track sequence "bell - "ad"
represents a K+ meson decay (and not 7-~L- e).
The "ball particle of momentum (113�22) Mev/c and
d mass (195�55) Mev corresponds to a pion or a muon.
Since the track ends with a nuclear disintegration,
I "ball is considered to be a pion. Some other pos-
01 sibilities of decay modes are discussed, as for
b 1170 40 example, K0+n --* n+K++n-. But, on grounds explained
0 c here they have very small, probabilities. The only
probable interpretation of the observed decay
remains the mode DO - K++w~'+ Q with Q = 10 50 Mev.
-,a The mass of Do is taken to be (660+50) Mev and the
mode of production is assumed to b-e P- + P --Pn + Do.

ABSTRACT. Visual observations of auroraq boreales by the Network of
Hydrometeorological Stations in the Ukraine under the MGG-Prog-
ram were made at 16 stations. In 1957 nine aurorae bereales
were observed; from January 2" to 22, on July 1, from September
3 to 5, on September 22, from September 29 to 30, from Octo-
ber 19 to 21, and on October 31. In 1958: on February 111, May
14, from July 8 to 9, and from September 4 to rl. The three ilast
mentioned observations are mentioned in the records of the mag.
netic Station of the Akademiya nauk USSR ( Aca-demy of Scienc.?s
of the UkrSSR) at Demidovo, near Kiyev. This station was estab-
lished in the spring of 19,58. Aurorae boreales were further cb,
served on the Crimea, in Odessa, and o-~her Soutiern regions.
They coincided with the most active magnetic storms. In many
cases, however, magnetic storms were not accompanied by any po-ar

~ABSTRACT: For certain investigations such as the study of the structurel
,of fogs, frosts, dry winds, etc., separate measurements of ascending andl
idescending radiation fluxes is of great importance. This paper describesi
I
:a two-sided pyrgeometer used for separate flux measurements. This
1pyrgeo-meter consists of two standard balancemeters, one placed above thel
'other with a black body between them. The black body consists of two L-
i I
1plates made of thin copper foil with a thermoresistant, flat, bifilar
I
Ispiral between them. Both sides of the black body are blackened with
;Dutch niello. The temperature of the body is controlled. All sensitive!-
Isurfaces are subjected to constant forced ventilation. Unlike the
Card

ACC NR- AT6031972
;Courvoisier instrument, temperature differences outside and inside the
i
!balancemeters are measured in this pyrgeometer. The balancemeter
linterior receives radiation from the black body which has the tempera-
iture of the surrounding air because of the intensive, constant, forced
'ventilation. The length of the ventilation shaft is many times larger
than-the thickness of the airflow ventilating the black body and balance-
'meters, which provides thermal stability to the flow and eliminates the
high temperature gradient inside the instrument. An advantage of this
I
linstrument is in the separat 'e measurement of radiation fluxes relative
1to the radiation of the same black plate of a certain temperature with
1constant ventilation of all sensitive surfaces. The two-sided pyrgeom-
leter was presented at Tashkent in September 1963 where it was tested
lunder conditions of high temperatures, clear air, and weak wind during
the day and at night. The values of soil radiation. measured with the
pyrgeometer, changed slowly with the change of soil temperature under
the instrument, Uhile the atmosphere radiation changed steadily with the
sunts elevation. The pyrgeometer conversion factor has been derived on
,the basis of graduations of the black body. It is established that the
mean s4uare deviation of the balancemeter conversion factor depends on
the value of the given balance; the error decreases if the balance
!values are in the range of 0.2-0.5 cal/cm2.mins Ventilation insta-

ABSTRACT: In Qctober-November,pf 1961, the UkrAinakiy n.-i. gidrometeorologi-

made a series of frequent soundings of the lower part of the boundary layer of
1 the atmosphere with strings of captive balloons and a sensor developed by the
author. The investigation vae'to'clarify the characteristics of blocking 'and

corresponding to the development and disappearance of much layers. Such data are'
needed for developing methods of artificial fog owdification. The literature

ithe entire bou;idary layer gradient, although the investigated phenomenon in re-
sponsible for disruption of the monotonic change of meteorological elements with
height often occurring in fogs. The nonhomogeneous structure of the lover
layers can affect greatly the conditions for development and disappearance of
20
fogs. An effort~vas made to detect deviationA exceeding 0. from the smooth
vertical distribution of temperature. ',The method used has been described earl-
j-ier; semiconductor thermistors were used an sensing elements. The instrument,
was carried aloft by balloons (radiosonde envelopes Non. 100 and 150); the cap-
tive balloons ver:e spaced at 10 or 15 m intervals; sounding series lasted 8-10
hours; height of sounding ranged from 100 to 240 m. These data were supplemented
by radiosondeand aircraft sounding data. Synoptic conditions during the inves-
tigations are described. Significant results are shown in Fig. I of Enclosure.
Inversions and bl 'ocking layer's with small vertical extent were observed during
change of temperature and humidity profiles from unstable to inversion and vice
.versa. Change of profiles"did not occur gradually from bottom to top or top to
~bottom but by change of stratification in individual relatively thin layers.*

ABSTRACT The new machine permits a simultaneous examination of 24 samplesi
as to small degrees of deformation and as to strength up to de-
ctruction. The machine consists of two columns which are firmly
mounted on a cast plate. A silumin plate with draw bolts is fixed
above them. This forms as a whole a closed system which serves
for the neutralization of the vibration phenomena occuring during
the operation of the machine. Between the columns there is a fur-
nace for the warming up of the samples (up to 11000). If it is
necessary to raise this temperature up to 12ooO a furnace with si-
lican carbide inset is used. The operating space of the furnace
permits the bending of the samples up to an angle of goo. The tem-
perature is controlled here by a thermo couple and the contact gal-
vanometer. Current is supplied by two voltage regulators PHO'250-5p.
A shaft of refractory metal is mounted vertically in the center of
the furnace on which there is a disk with a clamping device for
fixing the samples. This shaft is driven by an elastic transmis-
sion of an asynchronous motor up to a frequency of 40oo/min. The
Card 1/2 shaft has a fly wheel outside the furnace. In one of the ground

columns of the machine there is a lifting device with a brake
for the lifting of the shaft from the stove as well as a lateral
displacement. In the upper part of the shaft there is a speedo-
meter for the control of the frequency of the shaft and of the
disk with the sample. The samples (rods) fixed tolhe middle of
the disk have weights on their ends which can cause at given fre-
quency a centrifugal load up to about 7o kg/mm2. The bearings of
the shaft have a cooling device. This machine can be used for
short as well as for longer examinations of refractoriness and
admissible degree of heat of the samples. There is1drawing in the

INTRODUCTION: This book, of which a Phase I Exploitation (SOV/1200)
has been prepared, is a collection of scientific papers devoted to
the study of titanium and its alloys from three main points of view:
physical metallurgy, forming, and welding. Special problems In-
vestigated include structural changes occurring during welding, de-
termination of the sontent of harmful gases, development of Indus-
trial methods of rolling, and oxidation at various temperatures.

The purpose of this investigation was to develop a satisfactor7
method of hot-compacting titanium powder. The authors first at-
tempted hot compaction with graphite compression molds, which,
however, proved unsatisfactory because the titanium reacts with
the graphite and the molds can be used only once. The authors
therefore used a new complex nickel alloy (composition not given]
developed at the Institute of Metallurgy at the USSR Academy of
Scineces in 1953-54. This alloy is some 40-50 times stronger than
pure Ti at 950-10000 C. The alloy can therefore be recommended as

a, material for compression molds for hot compaction of powdered
Ti, Be, Zr, Ni, Fe, Th, U, and other metals. Compression molds
of the new alloy were made in the following shapes and sizes:
1) dylindrical, with 15-mm %diameter, 20-mm.height, and 15-g.
weight; (2) cylindrical, with 45-mm.diameter, 60-mm,height, and
approximately 400-g.weight; (3) rectangular, 6x6x6O mm, 10 g.in
weight. These molds were designed by one of the authors (V.F. Prok-
hanov). A study was made of the effect of temperature, specific
pressure, and duration of hot compaction on the density and hard-
ness of the compact. Hot compaction of CaH2-reduced and Mg-reduced
Ti was carried out at 800', 8500, and 9000 C, at a specific pressure
of 15 kWM' . and for periods of 0.5 to 30 minutes. An investigation
was also made of the hot compaction of Ti alloys contal'Ung 5 per-
cent and 7 5 percent of Al. These tests were carried oRt at a tem-
perature oi 8500 and at a specific pressure of 15 kg/mm~ after pre-
liminary sintering at 10000. Conclusions, 1) The new heat-resis-
tant nickel alloy may be used for making-compression molds intended
for hot compaction of metal powders at teWperatures of 800-1000* C
and at a specific pressure of 12-15 kWmm . 2) It was established
that the theoretical density of Ti is achieved by hot compaction

with a specific pressure of 15 kg/ at 900' after 10 minutes, at
8500 after 20 minutes, and at 8000 after 30 minutes. 3) In the
case of powd:ered titanium-aluminum alloys containing 5 percent and
7.5 percent of aiuminum, hot compaction at 8500 with a specific pres-
sure of 15 kg./mm. for a period of 20 minutes is sufficient to obtain
a density equal to 98 percent of the theoretical density of the alloys.
