ABSTRACT: A method is described for calibrating RUP-1 radiometers with a
minimum of 1076 accuracy. Results of calibration of thermal neutrons in a diffuse
field and in a directed stream were compared. It was found that radiometers
calibrated in a directed stream showed a reduced magnitude during measurements
in a diffuse field. As a rule, diffuse fields occur in real conditions, therefore,
readings of radiometers calibrated in a directed stream must be increased during

ABSTRACT: A method is described for adjusting radiome
similarity of radiation fields produced by neutron sources. The methods were
tested with an all-wave counter and RUP-1, KPN-1, and KDUS-lM radiometers.
The discrimination threshold in all instruments was set up so as to make it possible
to discount the effect of gamma radiation. The results of the adjustment of neutron
radiometers by the method of similarity of the radiation fields were compared With
the results of the calibration of the same subrange. In all cases, the results of them

adjustment and the calibration coincided within the limits of measurement error.
The economic advantage of the method of similarity for the adjustment of radio-.
meters is evident. In this case, the limits of radiometer calibration extend two
or three times, the measurement time is reduced, and working conditions are
safer from radiation. This compensates for the small decrease in the accuracy
of the determination of neutron flux density with radiometers adjusted by the
similarity method.

TOPIC TAGS: radiometer, thermal neutron
ABS MICT: The possibility of using a graphite moddrator as a source of thermal
neutrons for calibrating neutron radiometers was explored. A rast-neutron source
I (T(d,n)He4 reaction) was placed inside a cavity in the graphite. With thick indus-
Urial ZrT and TiT targets, the neutron yield reached 109 per sec, at 100 kv and
&00(dam,p in the cascade accelerator. Theoretically, Q/P = 7000 per =2; experiment
5600 per cm2; here, Q - yield of fast neutrons, P - thermal-neutron flux density.
ience, a field of thermal neutrons with a density of 106 neutr/sec.cm2 was feasible;.
these neutrons had a Ma.-.caellian energy distribution and a temperature of 293K.
The technique of calibration of Soviet-made RUP-1 radiometer is described in some
detail. The radiometer calibrated in a directional flux showed readings by 3C0
I lower than true value6fmeasurand when used in diffused fluxes. Orig. art. has:

with each other. Further results are given and discussed. The ana=

make possible a unique choice as: yet. But the totality-of the
experimental data on the photodis-integration of the nuclei B~9

PERIODICAL: Koks i Khimiya, 1959, Nr 2, Pp 43 - 48 ~USSR)
ABSTRACT: Standard methods of determining naphthalene are criticised.
The authors carried out some experimental work in order
to develop a more accurate method for the determination of
naphthalene in scrubbed coke-oven gas. The picrate j;ethod
was taken as a basis and the influence of the following
factors on the accuracy of determination was studied:
method of purifying gas from accompanying naphthalene
compounds and experimental conditions such as filtration
of naphthalene picrate, titration of picric acid obtained
from the decomposition of naphthalene picrate and increased
velocity of gas during absorption of naphthalene. The
experimental results are given in Tables 1-3. The
possibility of obtaining more accurate results by the
picrate method with the following modifications was
established: a) filtering off of the naphthalene picrate
obtained should be done using a crucible with a porous
bottom (Nr 3) which considerably reduces losses of the
Cardl/2 precipitate (in the standard method, double filter paper

SOVJ68-58-2-12/20
Determination of Naphthalene in Coke-oven Gas
is recommended); b) titration of the picric acid formed
on the decomposition of naphthalene picrate should be
done iodometrically; the neutralisation moment is
determined on the basis of a sharp change from green to
yellow colour; c). the absorption of naphthalene from
gas can be done at velocities of about 100 litres/hour,
which shortens the analysis from 10-12 hours to 3-4 hours;
d) before the absorption gas should be purified from
accompanying naphthalene compounds which are able to form
complexes with aqueous solution of picridiacid with 75016
solution of sulphuric acid. There are 2 figures and
3 tables.

TITLE: Position of the Giant Resonance in the Dipole Absorption

PERIODICAL: Zhurnal ekSDerimentallnoy i teoreticheskoy fiziki,
1960, Vol. 39, No-1 (7), PP. 108-111
TEXT: The shell theory has already been used by Wilkinson (Ref. 1) to
calculate the dipole absorption of gamma quanta and to explain the width
and area of giant resonance lines. It was, however, found that the
theoretical giant resonance energy was about twice as high as the experi-
mental energy. Attempts to avoid this difficulty by introducing an "effec-
tive mass" led to an increase in the spacing between neighboring single-
particle levels (- 14 Mev), whereas the value of 6-7 Mev was experimental-
ly confirmed. In the present article the authors show that for nuclei with
A e- 70 a consideration of the residual pair interactions in the calculation
of giant resonance according to the shell theory yields values which agree
with experiments, without the necessity of introducing an "effective mass".

there is sufficient spectroscopic material available. The calculations

V51, such as the transition M: (Pf7/2)"('f7/2 ) 3 __* ()) f 7/1 ) " (Y d 3p (V f5/2)

sources are given. The energy of transition (1) was estimated to be
19 4 20 Mev. Formulas for the absorption cross section are given for
a) trarsitiona from incompletely, filled shells and b) transitions from
filled shells. The results (El-absorption curves) obtained for
V51 and Ca40 are shown in the first diagram; the o her three diagrams
contain the curves obtained for Ni58, CU63, and cu 5 as compared to the
experimental curves determined in the papers of Refs. 13 and 15- Satis-
factory agreement is found also in this case. For the three last-mentioned
isotopes, however, the experimental material available is comparatively
poor, so that the results are not very exact. Finally, the authors thank

TEXT3 The angular and energy distributions and the photoproton yields
from Pr141 have been measured for the maximum bremsstrahlung energies of
22-5 and 33.5 Mev. The experiments were carried out at the betatron of
the NIIYaF MGU (E rmax - 35 Mev). Experimental arrangement (Fig. 1)j The
gamma quanta from the betatron target 1 passed through monitor 2, the lead
collimator 3 and through the magnetic fiela 4, and entered the vacuum
chamber 6. In this chamber was a metallic Pr foil which was tilted from
the gamma beam by 300. The emerging photons are recorded photographically
,sing NIKFI plates with T-3 (T-3) 400t. emulsion and R-2 (Ya-2) emulsion
as well as Ilford C-2 plates. An auxiliary magnetic field kept the elec-
trons leaving the target from striking the photographic plates. Results

protons from Pr141 photo disintegrations at E rma x . 22.5 and 33.5 Mev.
The curves I and 2 correspond to the calculated spectrum of evaporated
protons and of protons from direct photoeffect, respectively. Background
was taken into account; generally, it -was N5%, but reached rj20% at 300.
The angular distribution may be described by the empirical expression
a -i- b siu 20(1 -;- p 0080)2(1). The values of a, b, c are given in Table 1.
As an example.. Fig, 5 shows the angular distribution in the energy interval
of from 7.25 10 11.25 Mev (1 - E rmax ' 33.5 Mev, 2 - E 4max - 22.5 Mev).
Conclusionss (1) The maximum of the photoproton production cross section
corresponds to gamma energies above 22 Mev- (2) The gamma absorption in
this range has quadrupole character chiefly. This follows from the ex-
pression (1 ') and from Table 1. (3) The principal peak of the spectrum for
Etmax - 22.5 Mev corresponds to the transitions 1g 7/.2_-1h9/2 and
1g 7/'2--3"2f 5/2 . The peak of the 33.5-Mev spectrum corresponds to dipole
transitions as well as to quadrupole transitions with chiefly

TEXTs The cross section for the diDOle absorption of,(,~-quanta by Pb 208
nuclei. has been calculated by using the shell model. The application of
the diagonal approximation (taking into account only the diagonal terms
of the interaction of the particle with a "hole") to the photodisintegra-
t1or of Pb 208 does not bring about an essential change in comparison with
the single-particle model of Wilkinson. In this approximation, the curve
of dipole absorption is characterized by a wide maximum in the range of
5.5 - 8 Mev (experimental range 13.5 - 14 Mev). The energy levels J = 1-
and the corresDonding wave functions were calculated by diagonalizing the
in-leraction malrix, using the single-particle states shown in Table 1.
The position of the single-particle levels was determined in agreement

and an interaction amplitude of 1220 Mev43 (see W. W. True, W. T.
Prinkston, J. C,, Carter. Bull. Am. Phys. Soc., 5, 243, 1960), the values
given in Table 2 and Fig. 2 will be obtained forc< = 0.135. A relevant
calculation with the Wigner force resulted in values which deviated
considerably from experimental data. It is concluded that a consideration
of the residual interaction in Pb208 leads to an isolated "dipole state"
whose position corresponds to the experimental energy value of giant
resonance, The occurronce of this state is caused by the high density
of the single-particle Upole states in the nucleus under consideration.
It is pointed out that high density of single-particle levels is not a
sufficient condition fo:.- the occurrence of an isolated and strongly
~.orrelated dipole state (Brown-Bolsterli effect). It is assumed that the
&~_ant -esonance of P.iotodisintegration can be explained by the use of a
shell model and by taking into account "he mixing of configurations. The

ABSTRACT, In order to compute the cross sections of photonuclear reactions with a
sufficient degree of accuracy when working with bremsstrahlung gamma radiation of
betatrons it is necessary that yield curves be measured with exceptionally high
accuracy. Errors in experimental determinations are caused by the statistical
error in determining the yields of nuclear reaction products, error in determina-
tion of the energy of electrons in the betatron, drift 6f the instrument deterain-
ing the intensity of the flux of gamma quanta and the error associated with the
instability of the recording instrument in time. Most of these errors have been
eliminated or decreased by use of an apparatus already described in the. literature

(0. V. Bogdankevich, Atomnaya energiya, 12, No. 3, 199, 1962). An apparatus of
a similar type now has been constructed for simultaneous measurement of the yield
of photoprotons at three angles. The descriptive text is accompanied by a block
diagram of the apparatus; there are two synchronously operating units: a unit for
-regulating and stabilizing electron energy and a recording unit. The apparatus
was checked by measurement of the yield of photoprotons from zirconium. The re-
cording was for angles of 900, 900' and 1500 relative to the beam of gamma quanta.
The results are shown in.Fig. I of the Enclosure. "The authors wish to thank
