PERIODICAL: Izvestiya Akademii nauk SSSR, Seriya geofizi-cheskaya,
1959t Nr 6v pp 895-897 (USSR)
ABSTRACT: A method is described where the measurement of the velo-
city of transverse waves is not required. It is based on
the laboratory conditions of measuring the propagation of
the lonritudinal waves calculated from the formula
L
VPM W- ;' (I - a)/p(l +- a)(l - 2,or)j 1/2.
The samples of rock used in the investigations were syenite,
sandstone.and an alloy of aluminium for checking . The
measurement consisted of determining the ratio a/% PK
(a - radius of a sample, %P, - wavelength of P. wave).. It
was established that the velocity of

TEXT: The authors investigated the elastic properties of rock samples

medium (E - Young's modulus, 9 - density, 0 - Poiaaon coefficient);
the
experiments took place in a high-pressure chamber, in which the
pressure
could be varied from normal to 4000 kg/cM2. The ultrasotic velocity
was
measured by means of a pulse method, where a modified M KA-5 (IKL-5)

crystals were used; for the purpose of measuring Vp b, the
authors operat-
ed with 100, and for measuring Vp m with 600 kc/sec. The samples

results
of measurements are shown in form of diagrams, the assignment of
the
curves to the samples takes place according to the same numbers.
Fig. 1
shows the propagatio.1 rate of longitudinal and transversal
waves as func-
tionsof the pressure brought to bear upon the samplo. In
general, the cu,
within the range below 1000 kg/Om2 showud a steeper rise; in the
further
course, the pressure dependence of V is insignificant or V is
entirely
independent of pressure. Fig, 2 shows the Young's modulus and
the modulus
of shearing as a function of pressure. The course taken by this
curves is
similar to that in Fig. 1. The reaulto of the measurements of
the Poisson
coefficient at various pressures are given in Table 2:

ABSTRACT: The most important of the different age associations of
igneous rocks in
some of the structural zones of Northern Caucasus (the piedmont
region, the foot-
hills, the transverse depression zone, the granitoid zone and the
axial zone of the
Major Caucasus ridge) are described. The post-Selurian,
posi;-Lower Carbonaceous,
pre-Triassic, post-Lower Jurassic, pre-Middle Cretaccoxis and
~;enozoic formations are
described. The magmatic geology of Northern Caucasus is compared
with geophysical
data. A new scheme is suggested for the deep structure of the
territory. The
ancient basement is shown to consist of Hercynian and older
formations. In

particular, a substage of lower Hiddle Paleozoic formations is
differentiated. It
differs greatlyin respect to its physicaLl properties from younger
rocks of Upper
PaleozDic and Mesozoic ages. In the region of the Major Caucasus
this substratum has
been completely reworked by upper Paleozoic granitic intrusions.
Tht ancient rocks
outcrop in a few areas; however, to the East the Caledonian
basement is covered by
Mesozoic and possibly Upper Paleozoic formations. It is believed
that the deep
seismic sounding conducted near Ellkholovo has located the buried
extension of the
Caledonia structure of the Western Caucasian foothills. Orig. art.

ABSTRACT
y-Vanta
originate from the decay of neutral pions which were produced

in
the inner target of a phasotron by 660 MeV protons. These Y-quanta

were recorded by a pair-like y-apectrometer with 12 channels, on
which

occasion the spectrometer was at a distance of 23 m from the
target. Be-

fore the collimator, which was fitted behind a
protective wall of 4 m

thickness, a device was arranged, by which
the bundle of y-quanta was

periodically interrupted by means of a
lead absorber. The y-quanta record-

ed by the spectrometer in the
case of fully covered and not fully opened

bundles were counted
separately.

For the determination of the coefficients of the
absorption of the y-quan-

ta in Cu and Al the semicircular lead
disk in the rotating device was re-

placed by absorbers of copper
and aluminium. The frequent change of ab-

sorber3 made it possible
to carry out measurements without a monitor and

to diminish the
number of measuring errors. The bundle of y-quanta passing

through
the collimator was purified from electrons and positrons by means

of a special magnet. The authors obtained the following values (
in cm*/g)

for the coefficients of the absorption of y-quanta with
the energy of

The absorption of the y-quanta at Ey - 500 MOV takes-place
essentially by
the production of electron-positron'pairs. As shown by
computation results,
absorption by photo effect and Compton effect amounts to -, 1,2
O/o in
the case of Cu, and to -. 2 O/o of the total absorption cross
section ir
the case of Al.. The cross sections for the absorption of
y-quanta found
here agree w93.1 with the computed results obtained bf H. DAVIES,
H.BM,
L.MaIMON, Phys.Rev., 93, 788 (1954).
It remains to be added that the data for 500 MeV y-quanta which
agree with
computation-e were obtained in the case of permanent pre,,tence
of a lead
absorber of 5,55 g/cma thickness in the bundle. If suche'a lead
absorber,
by wbich the bundle-is filtered, is lacking, cross sections which
are
larger by 10 0/0 SA obtained. When measuring 41-he absorption
cross section
of 2~O MeV y-quanta, no influence was found to be exercised by
the additio-
nal absorber by which the bundle is permanently covered. The
cross section
of the absorption of 280 MeV y_cpanta obtained here agrees with
the re-
sults obtained by J.W.DE-WME, A.ASKIN, L.A.BACH, Phys.Rev., 83,
505
(1951). The reason for the increase of the absorption cross
section of
500 MeV y-quanta when an additional. lead filter was lacking
could not be
explained.

ABSTRACT: la a pair y-spectrometer the energy of the quanta is de-
termined by measuring the total energy of the courponents of
the electron-positron pair formed in a thin converter. The
first 2-chaimel pair spectrometer was built by Dzhelepov
(Ref4). Later spectrometers built on this principle were
widely used in measuring the s
.pactra of hard y-rays (ReLfs.2
to 8). The electron and the positron leaving the converter
were deflected by a magaetie field in different directions
and for certain values of their energy they enter ionisation
counters connected in coincidence. For a given intensity of
the magnetic field and a fixed position of the counters, such
a spectrometer will record a fraction of the pairs produced
by y-rVs in a given energy range. In a simple 2-channel
Card 1/6 spectrometer In which one channel records the electrons
and

the other the positrons, an increase ia the accuracy of
measurement is associated with a marked decrease in the
efficiency. Good energy resolution and high efficiency can
only be s:Lmultaraeously achieved in a multioban-nel
meter. In such a spaatrometer the efficiency may be inez~eased
by a factor r_jn2 without loss of resolution-,, where z~, and
n are the numbers of eleatron and positron counters. I-,
sich a spectrometer se'veral energy intervals may be i
at the same time. A number of suoh multichannel spect::~:-,.
meters have been described (Refs.5, 6 and 8). The
of a y-speetrometer as a measuring instrument is diAe3, ~,,
~.nf-d
by its effioienoy an& spoetral sensitivity. In
multichannel system it is necessary to take into aeoox
characteristics for the various pairs of channels of the
spectrum. In this connection, a discussion is given In the

tral sensitivity of the separate pairs of channels on various

1) Spectral sensitivit-V: the basic diagram of a y-speetro-
meter considered in M paper is shown in Fig.l. in whieb
the meanings of the symbols employed are indicated. In view
of the finite width of the counters, the spectrometer records
y-quanta in a certain energy interval from E y min to
RY max . The corresponding spectral sensitivity curve is
then shown in Fig.2a and is of triangular form with a dis-
persion given by

coUnter and ri and r2 are the distances from the con-
verter to the oentres of the counters, respeetively. The
effect of the width of the converter upon the spectral
sensitivity is examined and it is shown that a converter of
a finite width introduces a spread into the spectral line
in the high energy region of y-quanta. As the angle 9

containing n channels records y-quanta in n-1 energy in-
firvals of different mean energy. In practice, one seeks to
find the form of the spectrum and the absolute intensJt7 in
dne of the energy intervals. To find the form of the spec-
trum it is sufficient to know the relative efficiency of
recording for the different energy intervals, and this is
given by Eq.(10). In order to obtain the absolute intensity
in one of the energy intervals it is necessary to know the
total absolute efficiency of recording of y-quanta in one
of the energy intervals. "Ohis problem is not treated.

ABSTRACT: Application of a multichannel pair spectrometer in
synchro-
cyclotron work presents a number of specific requirements as
far as counters of the ionising particles and the electronic
system of the spectrometer are concerned. Since the beam
intensity is high and consists of short pulses of 200 to
300 lis each at a repetition frequency of 40 to 80 pulses per
see it follows that the apparatus must be very fast. ..It is
desirable that the input blocks should have resolving times
not greater than 1 lis. The large background intensity in
synchro-eyelotron work means that it is always necessary to
use a special selection system which records only electron-
positron pairs. 'For this raason, in the spectrometer each
component of a pair should be recorded by a number of counters
in coincidence with sufficiently low resolving time. The
Card 1/7 present paper describes a 12-channel y-spectrometer
which has

been used over a number of years in studying the spectra of
hard y-rays and neutral Ir-meson decays (Refs .2-6). The
first variant of the spectrometer was built in lc)49. In 1951
and 1954 the spectrometer was modified to improve its --harac-
teristics. The spectrometer described here satisfies com-
pletely the above requirements and is based on the design
calculations given in the previous paper (Ref.1) in th--'-s
issue.

electrons and positrons was used, and this led to increased
efficiency (Ref.1) because it was posRible to use wider and
thicker converters. For y-quqnta in the energy range 450-
600 MeV, 2v - 900 but the counters were at a larger distance
from the converter. Copper converters were used (0.1. 0.3
and 0.5 mm, depending on the energy).
2) Resolving power and efficiency.
Fig.2 shows curves of the total spectral sensitivity for the
7th energy interval for various values of E YO and thick-
nesses Tk of the copper converters. These curves are based
on the theoretical data given in the previous paper and are
obtained by a statistical combination of the partial distri-
butions due to a) width of the counters, b) width of the con-
verter, c) multiple scattering and d) radiation. As can be
seen, the form of the total spectral sensitivity curve is
VexV nearly triangular which means that the total spectral
sensitivit7.is governeA mainly by the width of the channels
t. (see Fig.1 of previous paper, p 24, this issue).

3) Counters and selection system. The counters used were
proportional counters having a Fylindrical stainless steel
cathode, 10 mm in diameter and a molybdenum filament 0.1 mm
in diameter. They were filled with (CH2(OCH3)2) at a
pressure of 160 to 200 mm. The working voltage was 1600 to
2000 V. Th~ counters have an effective dead time not ex-
ceeding 10 see. The efficieney of the counters for par-
ticles with relativistic ionisation reaches 918% in a coin-
eidence scheme with a resolving time of 5 x l&-7 see. The
delay of the pulses due to dri;(t of electrons through the
coun-ter San is less than 10-Y. The counters give. electri-
cail pulses with amplitudes between 10-4 and 1 V. The large
difference in the amplitudea requires the use of amplifiers
having a wide dynamic range and an amplification of a few
thousands. 6-fold coincidences were used and the number of
random coincidences in each 6-fold channel was 0.02 pulses
per see. The number of eleetron-positron pairs recorded per

sec depended on the efficiency of the spectrometer with
respect to the y-quanta in the measured energy interval and
the form of the spectrum and was in the range 0.1 to 10 pairs
per see.
4) Bleetronio scheme.
A block diagram or the electronic part of the spectrometer is
shown in Fig.3. Tts) left-hand portion of this diagren shows
6 co-ordinate counters of the electron series (a, - ad, 6
co-ordinate counters of the positron series (Bi - 3.) and
4 selection counters (All, AnI V and 'U"). Each of these
counters in practice consists of a gr,)up of counters whose
filaments are connected. A recorded electron or positron
should pass through 3 counters (1 co-ordinate and 2 selection
counters). A pair is recorded if a 6-fold'coincidence-takes
place. Negative-going pulses from each counter are ampli-
fied by a corresponding amplifier-converter (Fig.4). These
amplifiers have a rise time of 2 x 10-4 see. Pulses from
all the 16 amplifier-converters are applied to the main block
which is at a distance of 1.5 m from the amplifier-converters

applied to a

4-fold coincidence scheme while pulses from the co-ordinate
counters are applied to mixers and in addition through.delay
lines to a hodoseopic system consisting of 2-fold coincidence
circuits and output uftivibrators. The pulse at,the output
of a mixer appears in the presence of a pulse in at least one
of the co-ordinate counters of a givenseries. Pulses from
both the mixers and also from the 4-fold coincidence scheme
are applied to a 3-fold coincidence scheme which produces the
final output pulse. It follows that the latter pulse appears
when a 6-fold coincidence takes pl4c6,1.4p.when a particle
passes through at ledst one of the co-ordinate dountera in
the electron series, through one of th) co-ordinate couaters,
of the positron series, and all the counters of the se'Leetion
system. The resolving time of the above coincidence schemes
is 5 x 1o-7.

TEXT: Nuclear processes are considered in which transferred momenta
are
small also for large energies, and from whose theoretical
interpretation
it is possible to obtain data on it, xK, and KK interactions, as is
shown
here. This is shown for the process where a pion is produced by a
pion.
Use is made of the formula of Chow and Low which gives tho
relationship
between the cross 3ection for this process and the in interaction
cross
section for the case of small transferred momenta (Ref.1). It is shown
that this formula can be applied without much error for the
production of
a meson by a meson on a nucleus, and that it is thus possible to
obtain
data on in interaction from the total cross section for a nuclear
reac-
tion of the type x + A 4 x + % 4 B. This is true especially for the
