the stress caused by the plunger is transmitted to the water contained in the
limiter, and from there to the PREON-13 in the bubble chamber.
The limiter regulates the limits within which pressure in the chamber is modi-
fiedt it causes the pressure curve to assume the appearance of a rectangular
wave. The upper and lower limit value is determined by the pressure F 8 and Pi
in the left and right part of the limiter respectively. P. is 1,5 or twice as
high as the pressure of the saturated vapors of MON_1~9 and P is lower by
about 10 atm than the pressure of the saturated vapors, The ratio between the
duration of compression and that of expansion can be changed by changing the
quantity of PREON-13 in the chamber or the quantity of water in the limiter. The
pressure curve recorded by means of a capacity-manometer was observed on an
oscillograph. The bubbles cannot conglomerate during compression, they rise to
the top, and then conglomerate in a trap which is filled with cooled solid car-
.bonic acid. An attached photograph shows traces which were recorded with the
chamber. When the chamber was set up in the collar of a two-storeyed housep an
average of 5 cosmic rays per minute was observed. A rough estimate bf the degree
of efficiency furnishes the value of 0,1.

ABSTRACT: A description~is given of a x
of 20.x 11 x 10 cm5 non bubble chamber with a
working volume . The chamber is shown
in Fig 1 and is made of a single piece of stainless steel.
The chamber is cooled by 8 channels drilled through it. The
channels are connected in series with the RKF-0,9 refrigerat-
ing machine which forms a part of the installation. Thermal
insulation of the chamber is obtained by means of sheets of
plastic foam. The viewing glasses are made of plexiglass
45 mm,thick. The membranes M, and M2 are made of soft
rubber 4 mm thick and the packing between the glass and the
body is made of hard rubber 2 mm thick. A safety valve (Fig
2) is attached to the upper wall of the chamber. The charged
particles are let in through the cap 3 which is made of
dural 8.5 mm thick and has a diameter of 80 mm. The particle
tracksare photographed by a camera 8 _ Fig 5 shows a tYPi-
cal photograph obtained for 290 Mev Tf+-mesons. A detailed
deseription is given of the valve and the supply systems.

TEM During the irradiation of a two liter Xenon bubble chamber with
negative pions (momentum 3 Bev/o) in the ITEF AN SSSR (Institute of
ThAnretinal and Experim2ntal Physics 2f the AS USSR) 20000 photographs-
were taken. In their evaluation one was found, represented in Fig. 1,
which isassumed to disintegrate according to the scheme Do -".e + Ir.
Fig. 2 shows the geometrical scheme of this decay event. The chamber
worked without a magnetic field. Identification of the particl*s 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 "bell,which is stopped in the ohamber volume, was determined to
be (490�190) Mev, which agrees with the mass of the X meson within the
statistical error limits. The momentum determination for the "ad" parti-
cles gave the value (160�54) Mev/c, which corresponds to a X. 2 or K~"2
decay. Further considerations showed that the track sequence "be" - 'led"
IT- represents a e meson decay (and not Tr-,u- e).
The "ball particle of momentum (113122) Mev/c and
d mass (195�55) Mev corresponds to a pion or a muon.
Since the track ends with a nuclear disintegration,
0 "ball is considered to be a pion. Some other pos-
sibilities of decay modes are discussed, as for

0 0 here they have very small probabilities. The only
probable interpretation of the observed decay
remains the mode DO - K++,ri-+ q with Q - 10 1 50 Mov.
a The mass of Do is taken to be (660~,,50) Mev "d the
mode of production is assumed to be r- + n + Do.

Angular distribution of decay products from A-hyperons
produced by 2.8 BeV/C n--mesons acting on xenon nuclei

TUT: The asymmetr coefficients for the angular distribution of the
decay products of X_ hyperons were determined from 360 reliably
identified A -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 n +P -> KO+A. The relation ap- 0.27 + 0.12
holds for the up down asymmetry with respect to the plane of production
of the A-particles at mc:menta from 400 to 900 Mav/o in the coordinate
system of Fig. 2. a characterizes the degree of parity non-conservation
in the A-pa;ticle decay. With

-0-75 +0 15 the value 0.36+0 18 is deduced for the polarization
-0:50 -0:22
averaged over the production angle. Thil transverse polarization
depends on the momentum of the A-hyperon ih the laboratory system and
perhaps changes its sign at the momenta >900 Mev/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
perhapiL of the aame order as the effect itself), make it more difficult
to draw exact conclusions as to the amount of aP2' This amount
characterizes the forward-backward asymmetry. For all A-particles
produced according to n_+Xe 4A+K+Xel+nn, perhaps aP 3 ~ 0. The quantity
ap 3- characterizes the right - left asymmetry. Xel denotes the secondary
nucleus and an are the accompanying pions'. With 4 260 the asymmetry
ap3 is non-zero for all A with any momentum. There are 3 figures and 1
