ABSTRACT: In the*course of the evaluation of emulsion piles exposed in
the geographical latitude of Moscow at a height of 30 ka, a

an interaction. between a cosmic radiation proton and an

report about an analysis of the angular distribution of charaw
particles in this star. The energy of the primary particle

the authors (N h - 35) cannot be explained by the Heitler-
Terreaux theory. Figure 2 shows the differential angular
distribution of the shower particles In this star. The histo-
gram has two different maxima. For comparison, the curves for
isotropic distribution (in the ams), for Heisenberg distribu-
tion, and for distribution according to Landau are plotted.
It was found thato if it is assumed that in a nucleon-nuclous
collision the angular distribution does not deviate consider-
ably from that of the mesons formed in a nucleon-nuoloon
collision, the angular distribution observed can be explained
neither by Heisenberg's (Ref 6) nor by Landau's theory (Ref 7).
Figure 3 again shows a histogram of the angular distribution
of shower particles in the laboratory system. The curves
1,2,3,4 (in the ems) successively show Gaussian, isotropic,
and anisotroplo distribution for each of the two maxima
separately (in consideration of the energy spectrum of the
produced particles and on the assumption, that they are mono-
energetic). It may be assumed that the two maxima observed in

Issued: 12 / 1956
The average life of the charged 1-mosons of cosmic radiation was measured at
sea level with the help of liquid-sointillation-counters and of a high fre-
quenoy oscillograph. The arrangement and the mode of operation of the counters
in discussed in short, The time needed for development was
1,3.10-7 soo and the minimum time of growth in the amplifier was 20-16-9 s*o.
The error, which was found by experimenting and which is connected with the
fluctuations in time of the photomultiplier nU-10 remained below 10-9 goo.
A f=ther source of errors is mentioned.
ror the purpose of taking "post Impulse" of the multiplier and of the shifts
with respect to time between impulses (which occur an a result of the differ-
once in the time needed for the passage of two coupled particles) into account,
the distributions of the time intervals between impulses in the case of differ-
ent arrangements of the counters are measured. In connection with these control
tests the number of acts of decay in the counter itself was negligibly small.
The results of these control tests were taken into account when dealing with
the results.

The lowest energy of the decaying myon which was still able to obtain a re-
sponse from the measuring systemt amounted to 25 MeV. Thus the acts of decay
x 4 4" + V were eliminated. An act of d:cay eu -, 9 + 2 Y was able to cause
the device to respond, but because the re olving power of the coincidence
scheme amounts to 4-10-8 sea, the probability of such a response was suffi-
oiently small.
All in all, 64 acts of decay were noticed during 1600 hours of operation in
the interval of from 10-a to 4.10-8 sea. The integral distribution of the times
of decay is shown in a graph. The average life of X-mesons obtained is
(9,5 1 2t0).10-9 sea if a decay rule with an exponent is assumed. This result
is in agreement with those of several American works. Two further graphs
illustrate the scheme of the measuring system and the curve of the resolving
of the threefold coincidences.

ABSTRACTi A description and analysis of an oscilloscope f06 the
photographic investigation of pulses with 3 x 10 secso
rise time is given. The scope has been built in the Soviet
Union using Russian components. The signal is applied to
~ two stage pre-amplifier and via a 20 meter IIF cable%
~ phase inverter and push-pull output is applied to the
vertical deflection plates of a 5RPl-A CRT (since replaced
by a tube of Russian manufacture). A part of the 150-180V
signal is applied via an inverting pulse transformer to a
high speed time base using type 2050 thyratron. Part of
the scanning voltage is used for ti-IFgering the rtlay of
the camera shutter. The final vertical deflection amplifier
consists of 12 tubes t pe 6)K/ff in distributed amplifier
connection. Matching irom the pre-amplifier to the output
amplifier is achieved by means of a phase inverter designed
as a three tube distributed parameters amplifier with 6)KIrT
tubes. This amplifier has a gain of about 1 and band-width
of about 200Mc/s. The pre-amplifier consists of two

each stage - The delayed triggering is obtained using a
co-axial eable length of 200 ohms impedence between the
phase inverter and the pre-amplifier. Matching between
all stages is achieved by means of a 200 ohms impedence
for the grid line of the vertical deflection amplifier
and for the anode line of the hase inverter and of the
pre-amplifier. Artificial aUe and Grid lines are
m-derived filters with m 1.27. The load lines have
m-derived sections with m 0.61 which permits to keep
the wave impadence constant up to fz 0.8f . A detailed
description of all distributed line sectiSRs is given
(Ref. 5): the total bsin of the vertical deflection
amplifier is 500, its response flat up to 170�c/,-;, which
corresponds to a rise time of about 2.5 x 10- secs. A
detailed description of the fast time thyratron bace
generator is also given, two speeds being available for
the final anode voltage of 23kV: 130 and 40cm per psec.

as well as to evaluate the production cross sections. In the
first part of the paper the experimental arrangement (Fig 1)
is described in great dctail.. Within a system of Geiger-Mueller
counters there were 6 lead slabs of equal thickness (5o: g/cm2
and different sizel below this hodoscope system there were 4
liquid-scintillation counters, twc of which (C 3 and C 4) were
sy-..mctrically located cn the two sides cf an aluminum absorter.
These four counters were connected in triple coincidence
(C1 4C2#C3 (C4)). The cointillatiun counters are discussed aepara-
tely and are schematically represented by figure 2. Figure 3

TEM In an earlier paper (Ref. 1) the authors found that the intensity
of mesio X-rays 2P - 15 in U238 normalized to one stopped muon is con-
siderably less than in Pb. This fact indicates the existence of radiation-
le39 transitions in heavy mesic atoma, in which the energy of the 2P - iS
transition is not liberated in the form of an X-ray photon. It is assumed
that the probability of radistionless transition (W rX ) in mesic lead is
negligibly small in comparison to the probability (WhV) of a transition

vestigation. With the help of a scintillation spectrometer, the X-ray
spectra in the energy ranges corresponding to the transitions were
measured, Special attention was paid to determining the background level.
Figs. I and 2 show examples of the spectra recorded - I shows the
spectra of mesic X-ray photons from targets of Pb(4:4F6ig/cm2),
Bi(4,46 g/cm 2), and U238 (4.60 g/cm 2)1 as abscissa, the pulse height in

TEXTt The upper limit of a p -+ a +'y process is 1.6 - 2.0-10- 6 of all
muon decay events. This is probably the reason why such a process has
not yet been observed. Searching for this process the authors devised a
technique in which they operate with a spark chamber with high-speed op-
eration electronics. A 70-Mev R + beam obtained from the 680-Mev proton
synchrotron of the LY&P OIYal is separated out by the-coincidence monitors
1, 11, 0. The fast coincidences 0, 4P 5, 7, 8, -61 1, X and 0, 1, 2, 10,
11, 7, -17, 1 with a time resolution of about 10- 8 sec actuate a master
signal which startr up the pulse generator for the chamber. The traces
in the chamber were photographed from two sides. A third camera recorded
the oscillograph, from which was measured the time between signals of the
coincidences 1, 11, 0 and 0, 4, 5, 7, 89 16, 7, X or 0, 1, 2, 10, 11, 31

T~, 1. The six-layer cylindrical chamber 1; was to record the electrons
and gamma quanta. The error in the determination of the collinearity of
events wag 4.80 across and 200 along the chamber. The efficiencies of
53-Mov electron and gamma recording, were 40 and 15 ~, respectively.
However, the general efficiency for p -+ e + y events was only 0.8
The results of the authors' measurement showed that unlike earlier
estimates the upper limit of p --~ e + y decay processes is 5*io-7.

Fast coinciden6es of any pair of lateral counters with a central counter
generate a control signal which is amplified and fed to the high-voltage
electrodes of two spark chambers. The particle tracks in the +chambpre
are photographed and the interval between the stoppage of a x meson and
the generation of the control signal is measured simultaneously. The
