A pulsed fast reactor B100214
decrease of 2-1#1 %1 the rough regulator allows a
reactivity change of
2.4 %, the manual regulator.0.1 %, and the automatic
regulator 0.036 %.
The reactor possesses also a reactivity booster for the
production of one
intensive pulse. The control and shield system is an
automatically
functioning electronic arrangement with BP 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
important experimental arrangement consists of a 1000 m
long neutron
coxiductor, 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 Hg is
maintained. This
conductor connects a chain of socalled "intermediate
pavilions" (at
distances of 70, 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

assemblies and slowly moving main block for the determination
of the most
important parameters of the reactor; experiments with a core
assembly
(unmoved), experiments with rotating (5000 rpm) main block and
a Ra-a-Be
source in the core for the investigation of the effect of the
multiplioa-
tion factor, etc. The most important results are represented
graphically.
For example, Fig. 8 shows the dependence of the half width 0 of
a pulse on
the reactivity; the dashed line holds for the uesietationary
caset the
dot-dash line for the.case of G - MTN 1/3V-27 where v is the
velocity
of motion of the (rotating) main block; in the quesistationary
case
0 - 24Em/av where em is the reactivity at the maximal
multiplication
factorl F_ = FIM-ax 2, 'Where x is the displaaement of the main
block. The
reactor has been actually used for the measurement of the
total, scattering,
capture, and fission cross sections by the time-of-flight
method. Further
experiments will be carried out with a view to obtaining
increase of power
and decrease of the pulse duration. There are 15 figures and 3

combined
allW-interactions in the upper nodes of the diaVrams A and B. The
ratios of the cross sections for even and odd numbers of mesons

The*peripheral

decisive
mechanism. The experimental data are not reliable and the

TEXT: The author shows that the cross section of elastic back

in the laboratory system decreases with the energy E of the
interacting
0
particles as evl/Eo. This result was obtained on the assumption that
spin
effects are negligible, that the wavelength is small as compared with
the
dimensions of the interacting particles, and that absorption is high.
The
results expressed in the form of the differential cross section of

PERIODICAL: Atomhaya energiya, v. 14, no. 1, 1963, 105-109
TEXT: A detailed discussion is given of the significance attaching to
the causality principle in classical and qiiantum physics (cf. also.

attempt:.-is made.
to avoid the divergencies that.result when the causality principle.in
the space time continuum is applied on the microscopic scale. A
discus-'.:~
sion is given of the theoretical possibility of preserving macroscopic
causality and of so modifying microscopic causality that no
singularities
appear. In this connection the possibilities for'a suitable
generaliza-
tion of the causality principle are discussed. buch possibilities may
arise'from the nonlinear theory of. field propagation (Born), the
change
.of the metric of the physical vacuum and the space time quantization.

do not contradict relativistic Idnematics, which hold on the
average with an
I accuracy of -1A. Ilia dependence of mass on velocity has been
verified with higher ac-1
curacy, up to 0.01%. Possible large deviations from relativistic
kinematics are con- i
ceivable, but these have low probability and have not been
investigated. The only I
troifulesome aspect is the situation with local field theorY, which
is closely related
!to the assumed form of geometry and to causality. Asymptotic cross
sections in the
irc~-ion of 20 Gov do not approach one another as expected, and a
comparison of present_
3,y known data on the forward scattering of high-energy pions does
not agree with the
-results of calculations by means of dispersion relations. This
calls for an increase
in the measurement accuracy. If this disagreement between theory
and experiment is
i sic!
jeonfirmed, this would serve as a serious basis for a radical
reevaluation of the ba,
ipostulates of modern special relativity theory. Orig. art. has: I

ABSTRACTs Certain requirements for signal linearity Implicitly
contained
In the special theory of relativity are usually Ignored. Eistein
has noted
many times that we must deal with the sum "geometry plus
physics," not
with each component individually. This article analyzes this
"sum" In
the example of an abstract world in which there Is only one form
of matters
the scalar field (X) distributed in space R (X) (X - X I X2, x3,
x4).
In this case the directions In space R4 (X) are divides Into time
directions (within the zone of influence) and space directions
(without
It). In order to differentiate between space and timew It Is
necess 'ary
to employ a signal which has a cone of influence including all
other
possible cones of influence. The authors note that the Klein
equation, as usually appliedt leads to particle motion with
speeds higher
than the velocity of light, From the point of View of the
definition of
time given in this article (area attainable by a 'signal), the
author
considers that there Is one space coordinate and three time

ABSTRACT;
The
present report investigates the angular distribution of neut-

rona
which were obtained at the capture of a negative muon by a

proton
in 4&4-mesohydrogen. The negative muon is assumed to be po-

larized. In this case the angular distribution of the neutrons in

a general case will be generally anisotropic because of the non-

conservation of the parity with weak interactions, in which case

both the sign and the size of anisotropy depend on the form of

interaction.The energy of interaction of a nuon with a nucleon

taking account of the nonconservation of parity can be written

down conjugated complex in the form
H-5-~(V~,Okyp)(~[gk-gk't5]Ok-xt-') +
k

In this case Ok means the operators known from the theory of the

2-deoay which are composed of the Dirac matrices. It further

ABSTRACT: The investigation of the nuclear absorption of negative
muons
makes it possible to determine the non-electromagnetic in-
teraction between muons and nucleons. The process of the
nuclear absorption of muons develops via an intermediate
stage with formation of a mesic atom according to (I):
IL- + P --I- N + V + Q, (P - proton, N - neutron, V - neutrino).
In the introduction, several earlier publications dealing
with this subject are discussed. Most of the theoretical
papers, (as e.g. references 1 - 3), operate with the nuclear
shell model with j-J coupling. In reference 4 measurements of
the ratio between muon decay probabilities are compared with
the theoretical results obtained by Tolhook and Luyten
(Tolktiu'k., Luyten) (Ref 3) (Gamov,-Teller interaction type).

gation of the total depolarization of V -mesons in hydrogen.
In the present paper the authors investigate neutron angular
distribution from (1) when using g_-mesons, which are produced
as a decay product of u--masons polarized along the direction
of their flight. (1) may be considored to be a direct process
for the neutron angular distribution of which I + P 9acos 9 holds

tion of parity into account, the Hamiltonian for four-fermion
interaction between muon and nucleon is set up. As the binding
energy of the g -meson in the K-orbit in the mesic atom is

the muon can be used in non-relativistic approximation. For
the nucleus the shell model with J-J coupling is used. The
recoil energy of the nucleus is neglected. The potential of
the shell model and the interaction potential between neutron
and nucleus is assumed to be spherically symmetric. The spin-
orbit interaction of the emitted neutron with the nucleus
is not taken into consideration because this case has already
been dealt with.by reference 13. The results obtained by theo-
retical considerations are numerically evaluated for the
neutron emission probability dW(E NQ) and for the asymmetry

ried out with a coupling constant gk = ck(10-49 erg.CM3).

polarization of neutrons is calculated by basing on the

previous paper by E. 1. Dolinskiy and L.-D. Blokhintsev (Ref 1).
The formulas obtained,in this way hold actually only in the
case of nuclei with completely filled proton-subshells. Two
cases are investigateds The spin-orbit interaction between
neutron and nuoleus was 'I) neglected, and 2) taken into
account. The rather voluminous formulas for neutron polarization
in disregard of spin-orbit interaction are explicitly written
down. The even more complicated formulas taking account of
this interaction are not given. The formulas permit the
following conclusions toxbe drawnt 1) IneC-capture in mesic

TEXT: A detailed description of the apparatus is given.
Essentially it cons-ists of two coaxial cylinders, the inner space
being the working volume and the outer space'.for temperature
control. The inner cylinder is of copper to improve heat
transfer and the outer cylinder, together.with most of the casing,
is constructed from IX18ti9T (lKhl8N9T.) stainless steel.
Observation ports at the ends of the inner cylinder consist of-
dis s of JIK-5 (LK-5) glass 40'mm thick and with an aperture of
280cmm. Detailed drawings are given of the expansion apparatus
and the associated two stage double acting electromagnetic valve.
The nozinal gas pressure for operating the expansion apparatus is
7 atm and the.degree of expansion can be altered by changing the

details of the stereo-camera are given. The liquid nitrogen
supply system for the radiation shield and a 24 litre Dewar flask
,for liqitid hydrogen are also described. The magnetic field in
;the working volume is 12 kilo oersteds and is supplied by a
standard MC-4 Ns-4) electromagnet. Preliminary cooling with
'liquid nitrogen must be gradual and consumes about 100 litres.
iCracks were observed on the walls of the chamber when the cooling

!time was less than 8 hours. 'The time to fill the working volume

1with liquid hydrogen is about 3 hours and requires about 20 litres.
~During operation 2-5 to 3 litres/hour of liquid hydrogen are
~consumed. A photograph of a typical track showing the elastic
collision of a Tz"- meson with hydrogen is shown. The chamber-has
ibeen used satisfactorily for 6 months during which time
i30000 stereo photographs were obtained. The expansion apparatus
:has performed about 70000 cycles without changing the bellows.
