On the basis of the results described, the reac-
t-Al,on of precipitation isolated hapten and the
reaction of agglutination of mixed cultures cam
be reco'mmended as useful methods supplementing
the routine bacteriological examination. These
267T49
methods permit, a diagnosis within 24 bra, while a
:.bacteriological test require$ 3-4 days. The reaction
ot complement fixation (RSK) is not specific enough
and for that reason uncertain. The RSK procedure
developed by Ginzburg et al,at the Inst im.Mechnikov
fnot- further identifiefwas used.

ABSTRACT: The present work compares the experimental data for Y
(references 1-8) with the results of the calculations on
the below mentioned conditions. The authors investigate
the masses of only two frau-ments, namely !-light Olt a light
fra,-ment and 14hea of Fn heavy frag-ment. This corresponds
Ne way of fission. In the computation
to the most probab
of the energy of fission the mass '.',(A, Z) of the nucleus
subjected to fission was determined by means of the semi-
-empiric for-mulaof A. E. S. Green (reference 9), and the
masses M(Ali,lt, Zlir- t), IM(Aheavy, Zheavf) were computed
0 1 ~h
by means of the formula of Fermi with the correction
factors of P. Pong (reference 10) which take into account

char-es /~li-ht and Zheav of the fission fragments are
Computed uQInG the hypoNesis of the same P-decay chains.
The kinetik energy Ek of the fission fraGmento r~as
calculated by raeans of the formula Ek = cjZ2A-1i3(1 - C2

The constants cl and c2 are selected in such a way that the
last mentioned formula coincides best with the exDerimertal
values of~) in the equation of the balance of ener; . The

En consists of the bindinj~ enerCy Ebinding Of this very
neutron in the nuclear fragment and of its mean kinetic
energy 2T in relation to the frag-ment at rest. The
temperature T of the fra.Tment after the emission of the
neutron was estimated on the basis of the data on the
spectra of the fission neutrons of U233, U235, pU239

TITLE:
The Cross Section of the Fission of Pu 240 by Fast Neutrons
(Secheniye deleniya Pu 240 bystrymi neytronami)
PERIODICAL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1958,
Vol 35, Nr 2(8), PP 532-533 (USSR)
ABSTRACT: Thispaper measures the cross section of the fission of PU 240
with respect to the cross section of the fission of
PU 239 by means of a double ionization chamber. Layers of
PU 240 (2,5 mg) and Pu239 (4 mg) with a diameter of 5 cm were
fastened to a common hightension electrode, and therefore
they were located in the same neutron flow. The collecting
electrodes had the shape of hemislieres with a diameter of
14 cm. This apparatus permitted exact separation of the fis-
sion fragments from the a-particles. The authors give the
numerical values for the admixtures contained in the layers

The Cross Section of the Fission of Pu by Fast Neutmns
than 2 MeV were produced by the reaction T(p,n)He3, the 3
neutrons with energies from 2 to 4 MeV by the reaction D(d,n)He
and 15 MeV neutrons - by the reaction T(d,n)He4. The first
reaction was accomplished by means of a-Van de Graafe genera-
tor, the two others - by means of a cascade generator. The
fissions in both halves of the chamber were counted for fast
and also for thermal neutrons. The thermal neutrons were
obtained by slowing down fast neutrons in a paraffin slug.
The cross-section of the fission of Pu 240 was used for the
determinat on of the absolute value of the fission cross sec-
tion of puW. This cross section (in the plateau) amounts
to 1,50 + 0,15 barn and agrees with the results obtained
by Dorof~_eyev and D9rgnin. For 15 MeV neutrons the fission
cross section of pu 4 amounts to 2,6 + 0,2 barn. The authors
thank Professor A. I. Leypunskiy and f.- I. Bondarenko for
their interest in this paper and for useful comments. There
are I figure,and 2 references, 2 of which are Soviet.

TEXTs A layer of 4 mg of Pu 239 containing 1.80 + 0-05% of Pu 240
(thickness -0.2 mg/cm2) is built in a double fis_~ion chamber, and'is
irradiated with monochromatic neutrons. The T (p,n) He3 reaction is used
as the neutron source for which protons are accelerated by a 5-Mev
van de Graaff accelerator. The fission chamber was filled with 93% of
argon and 7% of carbon dioxide. The pressure in the chamber was 120 torr.
A broad-band amplifier connected the fission chamber and the c unter.
The ratio between the fission cross sections of Pu239 and Pu248 was
measured as a function of neutron energy, and the fission cross sectionkK

TEXT: The transformation of the amplitude distribution duo
to recoil protons into the neutron energy spectrum in the case of
a small crystal (negligible multiple neutron scattering) for
which the light output depends linearly on the proton energy, can
easily be carried out by differentiating the experimental
spectrum. In fact, in the case of stilbene which was used by the
present aAhors the relation is not linear and small crystals
cannot be used if an adequate counting efficiency is to be
obtained. The light output due to recoil protons and the form of
the amplitude distribution due to monoenergetic neutrons wag
investigated using a VCn do Graaf generator and the T(p,n)He3,
D(d,n)H*3 and T(d,n)He reactions. Neutron energies in the
following ranges could thus be obtained: 0.3-3.5, 4-7.5 and

If dE'/dx is expressed In Mev/cm of the range in air then kB turns
out to be 20 cm/Mev. Fig.3 shows the recoil proton spectra for
1.0, 1.8 and 3.6 Mev neutrons. These curves were obtained with a
cylindrical stilbene crystal (30 mm diameter, 15 mm long). The
curves have a hump at the high energy end which is due to multiple
neutron scattering. The latter effect is small for neutron
energies greater than about 2 Mov. It can therefore be neglected
at the higher energies. Fig.4 shows the energy dependence of the
resolution of the single-crystal spectrometer. The resolution in
the energy range 1-22 Mev can be described by the formula:

found to be about 3% at 2 Mev and about 0.5% at 10 Mev (the
differentiation step was taken to be equal to the energy
resolution t'~,En). The discrimination against gamma rays is
based on the differences in the effective scintillation decay

used the scheme suggested by Birks and described in detail by
F.D. Brooks in Nucl. Instrum. and Methods, 1959, 4, 151 (Ref.5).

The spectra of the fission fragments were recorded in the hemisphere in
front of or behind the layer. The ratio Q between the kinetic energies of
fragments released by fast and thermal neutrons was obtained from the
measured value of ~, taking account of all important corrections:
~ = Z + AQh + A~~I + 'AQV + LQ,. The correction terms al'low for the
losses in the layer, the ionization defect, neutron emission, and for the
motion of the center of mass. The results are given numerically. The
effect of the co 'rr6ction terms is insignificant and is only slightly above
the error of measurement. While the control substantially improves the
energy resolution, it hardly influences the values of Qp which deviate
very little from unity. The kinetic energy of the fragments does not
change when the excitation energy is increased to 5 Mev. The excess
excitation energy is almost completely consumed by the increase in the
fragments' kinetic energy. There arr 2 figures and I tables

that the individual properties of the produced fragments have a
