ABSTRACT: This is a continuation of earlier measurements of the differential cross
sections for elastic Yr+p scattering in a small solid angle about 180* at xt-meson
l.s. momenta 3-15, 4.10, and 4.85 (;ev/c, carried out at the High Energy Laboratory of
the Joint Institute for Nuclear Research, the results of which for 3.15 Gev/c have al~
ready been published (Phys. Lett. v. i7s 68, 1965). In this paper the authors present
the results for 4.10 and 4-85 Gev/c and compare the data obtained at all three ener- I
gies. The measurements at the different energies were made with the same setup, whict
was already described earlier. The ratio of the number of elastic wtmeson b;.ck?Aard-
scattering events registered by the apparatus to the total number of obtained photo-
graphs decreased with increasing energy (1:4.4, lt1l, and 1-.40 at 3-15, 4.10, and
4.85 Gev/cp respectively). ibis vu due not only to the deareas* in the measured

cross section, but to a deterioration of the background conditions as a result of the
smaller spatial separation of the recoil protons from the beam particles. It was
therefore required to apply more rigorous criteria for the selection of the backward
elastic- scattering events than earlier. The effective c.m.s. solid angle of the set-
up, calculated by the Monte Carlo method with account of the Coulomb scattering of
the particles, was 3-87 x 10-3 or for 4.10 Gev/c and 3.04 x 10-3 or for 4.85 Gev/c.
The effective cross sections, corrected for the nuclear interaction of the primary
and back-scattered jy+ mesons and the recoil proton in the hydrogen target and in the
counters, for the muon contamination of the beamp for decay of the scattered pion,
for the efficiency of the scintillation counters and the electronic circuitry, and
for the efficiency of the spark chambers, were (99 1 12), (74 1 ii) $ and (3T 1 12.)
jib/or for 3-15, 4.10, and 4.85 GeV/c, respectively. The previously deduced existence

ABSTRACT: The authors describe a method for monitoring the intensity of a neutro
n
source; this method is a modification of the "manganese bath" method originally
proposed by E. Amaldi (Phys. Rev. v. 50, 899, 1936). It is shown that it can be
used successfully to monitor exactly small changes in the flux of the fast neu-
trons during the measurement of absorption cross sections. The experimental setup
consists of a water tank (2 x 2 motors) with spherical cavity I motor In diameter,
in the center of which are placed the photonoutron source and the samples. Part
of the water volume is occupied by an aqueous soluticn of a resonant activator

ABSTFOCT This reactor is intended to be used for physical investigations
with fast neutrons. At fir~.t the active zone of the reactor is dis-
cussed. The heat-separat-,ng elements of the reactor BP-2 consist of
plutonium rods of lo mm diameter and 13o mr length. Besides the plu-
tonium rods there are similarly constructed rods in the active zo-
ne which are made of poor uranium. Altogether there are 1o8 u-
ranium- and plutonium rods which are mounted in a steel tube with
an inner diameter of 130 m!n. The reflector of the reactor consists
of an uranium layer (outer diameter 7oo mm) and a copper layer
(outer diameter looo mm). The reactor is controlled by a control
system and by an emergency system. The operating control organs are
part of a screen which are located near the active zone. The con-
trol system also contains boron-ionization chambers, an electronic
apparatus, and servofeeds. The emergency system enters into operat-
ion if the prescribed or assumed power of the reactor is exceeded.
Circulating mercury is used for the system of heat conduction. This
mercury is then cooled in a heat exchanger with water. The radiat-
ion protection of the reactor consists of the following parts:
Card 1/2 a) a water layer of 300 mm thickness b) a cast iron layer of 44D0 mm
The a-perimental Reactor for Fast Neutrons BP - 2. 89-6-1-24
thickness a) a layer of heavy concrete of l2oo mm thickness. A
special laboratory building was erected for the purpose of hous-
ing the reactor and its auxiliary installations.
Exoerimental Installations: The central experimental channel is
determined for the irradiation of samples with strong fluxes Of
fast neutrons. In the experimental channels in the lateral reflector
of the reactor also samples are irradiated, but also a local os-
cillator may be fitted. Three horizontal channels serve the purpa._a
se of conveying bundles of fast neutrons through the protective
casing of the reactor. The reactor furthermore contains a thermal
colurm of graphite, the dimensions of which are l4oo x 14oo x 2600 mm.
In conclusion the applicability of this reactor is discussed; in
particular physical constants are determined precisely.

TITLE: The Measurement of the Cross Sections of the Radiative Capture
of Fast Neutrons by Isotopes of Gallium
PERIODICAL: Atomnaya energiya, 1959, Vol 7. Nr 3, p 259 (USSR)
ABSTRACT: By comparison with the capt 15 cross Irtion of J 127 the
capture cross sections of Ga and Ga were measured, The
samples of the respective gallium isotope and the iodine
sample used for comparison were, at the same time, irradiated
by a fast neutron flux. The occurring P-activities were
measured by means of an end-window-counter. After the decrease
of P-activity, both samples were irradiated in a thermal
neutron flux and the occurring P-activities were newly measured~
By comparison of the activities occurring in both cases, it
was possible to calculate ax(n,y). The protons accelerated
in a Van de GraAf generator furn ished the fast neutrons with
the aid of the reaction T(pn)He . Within the energy range
of from 200 to 1400 kev, the neutron energy could be measured
with an accuracy of + 30 kev, and within the range of

influence of resonance- and fast neutrons-, the llcadmium"~,
method was employed. The results obtained are thown graphi-,
cally. In the case of Ga69 a smooth dependence of the capture
cross section on neutron energy is found. whereas in the
case of Ga71 a sharper decrease is observ'ed in the neighbor-
hood of 5c:O kev, This is probably due to the inelastic scat-
tering of neutrons on the levels 510 and 610 kev of Ga.71.

TEXT: The object of the work was to measure the radiative capture
cross sections of the isotopes mentioned in the title for neutrons of
energies of 0-03 - 2.1 Mev. The source of neutrons was the reaction
T(p,n)He3 carried out in a Van de Graaff accelerator. The sample activa-
tion by neutrons of energies En< 300 kev was measured at an angle of
950 with the direction of the proton beam in the accelerator; for neu-
trons of energies En> 300 kev it was measured at an angle of 00. The
error in neutron energy is due to the thickness of the tritium target,
the geometrical dimensions of the sampled and the fluctuations in the
accelerating voltage of the accelerator. For neutron energies of up to

200 kev the error amounted to * 1? - 20 kev; for higher energies it was

thermal column of a fast reactor. 127 and u235 were used as standards
for the cross section measurements by the method of reJative activation.
The zesults of measurement are represented in Figs. 1-4, their accuracy
being 2 - 5%. For neutrons of energies higher than 150 kev the results
for V51 and W 166 agree well with the measurements of Barshall; for

agreement is not so good. The capture cross section for Nb Is
essentially equal to the production cross secbion of the isomer Nb 94*

TITLE: Fast-neutron capture cross section for niobium, nickel, and
iron
PERIODICAL: Atomnaya energiya, v. 10, no. 3, 1961, 264-265
TEXT: The energy dependence of the radiative capture cross sectiom for fast
neutrons in a natural isotopic mixture of niobium, nickel, and iron has been
measured by recording the prompt gamma radiation. The reaction T(p, n)
served as neutron source. The'urotons had been accelerated in a van de
Graaff. The average spread of neutron energy was +20 kev. A scintillation
counter with a CaF 2 crystal was used as detector. The measurements were
performed in annular geometry. Measuring technique and evaluation are
describf:O in Ref. 1 (Moscow report). The energy dependence of the radiative
neutron canture cross section was obtained by a comparison with the course
of the U235 cross section. The experimental error of a single point does
not exceed I(Yj'. for Nb and 15P/~ for Ni and Fe. The radiative capture cross
section of 400-kev neutrons, which is 65 mb for Nb, B.3 mb for Ni, afid 5 mb

for Fe, has been used to determine the absolute cross section. The imults
of the authors' calculations are shown in Figs. 1-3 (full circles)
[Abstracter's note: As the three figures are very similar, only Fig. 3 is
presented] for Nb, Ni, and Fe, and compared with the results of Refs. 3-6.
If the cross section for niobium is averaged over many overlapping levels,
then the mean distances of the levels for nickel and iron are comparable
to the energy resolution of the method. The diagrams indicate that in the
range of 150-1000 kev, the radiative capture cross section depends only
slightly on energy. This is primarily due to the capture of neutrons having
a non-vanishing orbital momentum; another cause is the possible increase in
the radiation width with an increase in energy. A. I. Leypunskiy and
0. D. Kazachkovskiy are thanked for interest in the work. There are 3 fig-
ures and 7 references: 6 Soviet-bloc and 1 non-Soviet-bloc.

TITLE: A pulsed fast reactor
PERIODICAL: Atomnaya energiya, v. 10, no. 5, 1961, 437-446
TEXT: The present paper gives a description of the pulsed fast reactor of
the Ob I' yedinennyy institut yadernykh issledovaniy (Joint Institute of
Nuclear Research) which became critical in June, 1960. This reactor,
call ed H6P (IBR) reactor, serves as pulsed fast neutron source (mean
power Z I kw) for physical investigations, particularly for time-of-flight
experiments. its most distinguishing feature is the very amall.contribu-
tion (- 1o-4) of the delaycd neutrons in its normal operation; it is about

one hundredth of that of the usual steady uranium reactor. The pulses
appear because whenever the reactor becomes overcritical a burst of prompt
neutrons results. The half width of these pulses is 56 psec. The
frequency with which the pulses are repeated can be varied between 0 and
80 pulnev/seo. Fig. 2 shows the construction of this reactor. The
periodic change in the reactivity is brought about by the displacement of
the two U235 blocks placed in t-no disks that can be rotated. The main
block is pressed in the form of a disk, 1100 mm in diame;er, and can be
rotated with a peripheral velocity of 276 m/sea (at 6000 rpm) during which
it passes through the core center. The reactivity change obtainable from
the motion of the main block is 7.4 %, tfiat obtainable from the motion of
the auxiliary block is 0.4 ~-- The stationary part of the core consists of
plutonium lumps in steel jackets. The reactor is started by a rough
regulator, in this case a movable part of the reflector. It gives a
reactivity change at the rate of 13-io-5 -1.3-10-5 sec-1. The manually
operated rod is also a part of the reflector. Two plutonium rods in
electromagnetic suspension serve as scram. They can be separated from the
core with an acceleration of 20 g. Their separation causes a reactivity

2.4 %, the manual regulator 0.1 %, and the automatic regulator 0.036 %.
The reactor possesses also a re,:ctlvity booster for the production of one
intensive pulse. The control and shield system is an automatically
functioning electronic arrangement with BF 3 counters and ionization
chambers. The whole reactor is placed in a room of size 10-10-7 m whose
concrete walls allow complete protection from radiation. The most
imp,irtant experimental arrangement consists of a 1000 m long neutron
cox,ductor,'a metal tube, 400 mm in diameter in the first part and 800 mm
in the second part in which a pressure of 0.1 mm Eg is maintained. This
conductor connects a chain of socalled "intermediate pavilions" (at
distances of 70t 250, 500, 750, and 1000 m from the reactor) in which
experiments can be carried out. There Is also an additional neutron
conductor of 100 m length. The reactor chamber is joined to an experi-
mental chamber in which four neutron beams of up to 800 mm diameter are
available. There us such an experimental chamber also above the reactor
chamber. Various experiments were carried out with the reactor and they
are described in the present paper. These are experiments with stand

TITLEt, Plasma oscillations in ion-beam neutralization
PERIODICAL: Zhurnal tekhnicheskoy fiziki, v. 31, no. 10, 1961, 1202-1208
TEXTt The consequences of the condition that the total ion current in a
plasma vanishes have been studied. Electrons and ions are assumed to be
emitted orthogonally from a conductor surface at the velocities v 10 and
V20' Equations of motion and continuity for electrons and ions are
studied. For the potential T in the interviil 0,
