ABSTRACT: In the determination of the cross section of the immediate
production of electron-positron pairs by high-energy electrons
("trident" (troynik)) it is essential to know the number of
the so-called "peeudotridents" produced on a -.iven length of
the electron track. These "pseudotridents" are produced by the
conversion of the 7-quanta of the bremsstrahlung of the elec-
4. ron in the immediate neighborhood of its traclK. The authors
b
calculated the number of the "pseudo'bridents" according to
the Monte-Carlo (11onte-Karlo) method. These calculations were
carried out for nuclear emulsions for the following 3 initial

The cruss-section of direct production of electron-positron pairs by high energy
electrons was measured experimentally. For this purpose, a study was made ofisolated
electron--.hoton cascades and the photon component of high energy muclear interattions
in emulsion stacks exposed to adiation in the stratosphere. In order to exclude
spurious cases of direct pair production, which constitute the main difficulty in
experimental measurement of the cross-section of such pairs, the calculation was
carried out by the 14onte Carlo method.
The calculation wpa made for three values of primai-j electron ener&: 10; 100
and 1,000 Bev, taking into consideration two possible variants of the ~Temsstrahlung
spectrum: 'Bethe-Heitler and Migdal variants (Landau-Pomeranchik and Ter-Mikaelyan
effects). A method for deternining the ener&T of ultra-relativistic electrons from
the lateral distribution of the apexes of electron-positron pairs is suggested.
During the experimental measurement of very high electron energies, certain
possible soarces of underestimation were eliminated.
The cross-section of direct pair production by high enera electron:~ was found
to 1-~e in agreement with Bhabha's calculation within the limits of experimental error.

triplets were produced over that length. The dependence of th~

sults are in complete agreement with the theory of T. Murota et al.
(Ref. 20: Progr. Theor. Phys., 16, 4829 1956.). Hence the conclusion
that the available experimental results on direct pair creation by

ABSTRACT: The direct pair formation cross section for electron energies of
0-5 - 100 Bev has already been investigated several times
(Refs 1-13); the results differ considerably. The main experi-
mental difficulty is the necessary elimination of "false
triplets" (pair formation caused by the conversion of a y-quantum
of the bremsstrahlung of an electron immediately after its
production). Methods of evaluating that fraction Are discussed;
the most favorable theoretical treatment of this problem is
that by the Monte Carlo method. Also in the present paper this
problem is investigated by means of an improved variant of the
Monte Carlo method. The fundamentals of the calculation of the
absolute number.of false triplets for the primary electron
Card 1/3 energies 10 10 , 10 11 and 10 12 ev are given; the experimental data

?= VAY2 + Az2 is between 0.2 and 0-44~k (Refs 1,4,5). This
criterium is to be unified: Ay!!~- 0.2~4 ; Az -4- 0-44~4 , but also
for 0.3 and 0.66~A results are given. The diagram (Fig 2) shows
the dependence of the average number of false triplets R on the
distance to the primary electron; the values are compared with
the curves obtained by Weil as well as with those obtained ac-
cording to the spectra of Bethe-Heitler and Migdal (Ref 17).
Figure 2 shows the dependence of R on electron energy (again
compared with Bethe-fleitler and 11lig-dal). Agreement is satis-
factory. Further, the differential transversal distribution of

on the electron energy. The results obtained are discussed in
detail. The type of bremsstrahlung spectrum described by the
Migdal formulas also takes the Laridau-Pomeranchuk and the Ter-
Mikayelyan-effect into account. The possibility is shown of
measuring the energy of the fast electrons bj determining the
energy dependence of the mean transverse distance between the
vertices of the electron-positron pairs produced by bremsstrah-
lung y-quanta. In the last part of this paper experimental re-
sults are finally discussed, and it is shown that the cross sec-
tion of direct pair production calculated by Bhabha agrees well
with experimental results. The authors finally thank Professor
I. I. Gurevich for his interest and discussion, as well as Pro-
feasore A. I. Alikhanyan, K. A. Ter-Martirooyan and M. L. Ter-

TEM A statistical approach is proposed of investigating other-
wise little known physical characteristics of high-energy nuclear
interactions. The increase of the life-time of relativistic parti-
cles is discussed to show its effect upon enhancing nuclear inter-
actions of strange particles. In a medium of sufficient density a
considerable number of strange particles produced in primary colli-
sions will sustain nuclear interactions before having chance to de-
cay, due to the increased life-time~ It is shown that in secondary
interactions the proportion of strange particles in the particle
flux is always increased. For purpose of convenience the [ollowing,V

assumption is introducedg The nuclear (ineiastic) cross-sections
for strange and ordinary particles are assumed to be nearly equal
to each other and constant at a sufficiently high energy,. In parti-
cular, all the strong interacting particlea are aseumed to have the
same mean free-path for nuclear interaction kB for energy ;~ 5 Bev.
The JUBtification of the above assumption is discussed and at the
same time it is pointed out that its violation should not upset the
scheme in principle since it could be rectified by introducing ade-
quate corrections. A quantity proposed to be called "excess
ness" is introduced as followeg Two classes of secondary collisic...-
of energy E are distinguished 1) incident ordinary particles,
2k
2) incident strange particles. By identifying strange particles
of both classes one can determine the total positive strangeness
S+
2k and the total negative +strangeness S' 2k for the secondary collJ
siong and in almilar way S Ok and SOk are determined for the prima-
ry collision (e.g,, using particles from an accelerator) with the
same energy of interaction. The excess strangeness is then defined

SIk and S lk are proportional to the number of strange particles pro-
duced in the primary collisiong andq therefore, the quantity S
(SI + /S and its dependence upon Eo of the primary colli-,

sion describes the behavior of the strange particle production
cross-section. The proportionality between S 1 and the number of
produced strange particles would be violated if at some value of E 0
A -
intense production of 'r, and " hyperons occurred, since then the
increase of S 1 would include"the additional contribution of double
strangeness cascade hyperons. The behavior of the strange particle
production cross-section as well as the possibility of production
particles with strangeness 2 and 3 can be tested by looking at
fluctuations of Slo E.g. if the numbers of the produced strange
particles were distributed according to Poisson's law, the distri-
bution of S1 will also be a Poisson one with a standard deviation

-V-'~rjq 2-vul- or 3-VE-1 for respective strangeness 1, 2 and 3. An in-
dication of the production of strange particles of a higher than 1
order of strangeness can be this way obtained by a statistical ana-
lysis of experimental data; however, the expected effect will be
raiher small due to the comparative rareness of cascade hyperon
production. To assess the possibilities and requirements of the
proposed method a more detailed discussion is presented: 1) It is
observed that from a set of values of S:~ lk for different energies
E2k of the secondary collisions one can obtain information on the
energy spectrum of the primary collisions and the strange particl-~
production ctoss-section, assuming AB = const for energy :;;?=5 BeV.
2) Angular distributions of strange particles are considered. By
measuring the dependence of Steupon a mean angle of interaction
one can obtain angular charac ristics of strange particles produc-
tion in the-primary collision. 3) The problem is discussed of ob-
taining separate information on production of K-mesons and hypercns

ble since the small contribution of antihyperons can be neglected
and S+ will depend only on nuclear interactions of K + and K0 - me-
lk
sons. 4) From a known production cross-section at an energy E2k
the cross-section of the primary collision at a higher energy Bo
can be estimated by considering the ratio of the total excess
strangeness Sj/S 0. 5) Practical experimental possibilities are con-
sidered. The obvious procedure would be to apply the scheme first
to experiments using artificially accelerated particles to produce
the primary collisions; by combining previous information on stran-
ge particle production at an energy E 2k with those obtained at a
higher energy Bog it will be thus possible to step up the energy
until the limit available from accelerators is reached and then use
particles of cosmic radiation. It should be possible to carry out
these investigations up to energies Eo = 100 - 500 BeV, the limita-
tion being implied by the difficulty of identifying strange parti-
ales produced in collisions of such high energy. It is suggested, /

however, that by investigating ternary collisions using the same

to Eo = lo4 BeV. Finally a discussion is given of the experimental
limitations in terms of the required statistics and it is shown
that in order to obtain reliable data on excess strangeness in se-
condary collisions considerably statistics are needed, however, the
requirements are within experimental possibilities. There are 2 fi-

ticles
PERIODICAL: Akademiya nauk Armyanskoy SSR. Izvestiya. v. 14, no.6.
1961, 111-116
TEXT: The method is based on the relativistic nature of the inter-
action between traveling particle and electromagnetic field. It is
proposed observing the relativistic change in the distance between
the points where the particles and the wave peaks meet, by means
of thezadiation called forth at these points by accelerated ioni-
zation-electrons. In earlier works, the particle velocity was mea-
sured by standing electromagnetic waves, using the formula

method, as the apparatus would become too unwieldy. These difficul-
ties can be overcome.by netting tip a system of ranonator.9 along a
straight line, the resoriator.9 being excited with a phaje ohift

hator. The condition for the subsequent meeting in one of the oth-

mental conditions are considered which would involve an arbitrarily
small angle of incidencecy-',of the particles. Such conditions can be
realized by means of an apparatus consisting of 2 completely iden-

production of strange particles through primary interaction at high
energies is obtained by determining the yield of such particles from
secondary nuclear interactions and by comparing this with the yield of

ABSTRACT: Several.features that distinguish gamma rays produced

primary electrons. For example, in scattering of photons from-a

The energy distribution of the scattered 1Y quanta
becomes more monochromatic with increasing energy. 'Furthermore,
unlike bremsstrablung, the energy of the scattered quanta bears a one-
to-one correspondence to their angle relative to the direction of the
:pri ary electron. Tb~ number of/yquanta produced by a laser pulse of
~10-9 see can reach 10*-)--10(, which is comparable with the bremsstrab-
.lung yield. Advantages of this method of generating hard -fquanta aze
~the fact that the light can interact with the accelerated electrons
at any part of the acceleration cycle without being accompanied by
~extraneous background, and the high degree of polarization of the
.quanta produced. The availability of beains of polarized"Y quanta
with a favorable energy spectrum is of interest in the solution of
many pbysical problems, such as particle photoproduction and-.nuclear
photodisintegration. Orig. art. has: 4 figures and 18 formulas.
