TITLE: Chemical Effects of the Gamma,, n Reaction (Khimisheskiye effekty
reaktaii)
PERIODICAL: Uspekhi Mimii, 1957, Vol. 26, No. 2, pp. 164-175 (U.S.S.R.)
ABSTRACT: During the exposure of various elements by high energy gamniL-rays
an interaction occurs between the nuclei of the atoms of these
elements and the gamma-quanta, accompanied by the emission of one
or several nuclear particles. Such reactions are termed pho nuc ear
and have Very small cross sections (of the order 0.1-0.001 -~t cmi).
The gamma, n reaction is the best studied and generally has the
largest section compared to all other photonuclear reactions.
Radioactive isotopes with a shortage of neutrons form fr6m this
reaction., disintegrating for the most part by way of P !
disintegration or K-capture; many of these isotopes may be
used as radioactive indicators. Study of photonuclear reactions
began In the mid-19308, and the intensive and thorough investigation
of photodisintegration is now being conducted.
Card 115

Chemical Effects of the Gamma, n Reaction
A great step ahead was the application (in studies on the photonuclear
reactions) of gamma emission originating during the impingement of
Li and B protons according to the reactions:
Li (pj y ) Be8 .1
BIl (pj -Y ) C12.
The invention of electron accelerators (betratrons., synchrotrons)
made ROssible the derivation of gamma emission of any energy up
to 107 eV. More than 100 radioactive isotopes have been obtained
from the gamma,, n reaction but only 12 studies have been published
since 1950 on the chemical effects associated with photonuclear
reactions.
The author next presents general data on photonuclear reactions,
introducing the concept that Ethresh (Enoo ) (Threshhold of
photonuclear reaction) in order to separate the neutron from the
nucleus st be somewhat greater than Qn (the bond enerMr of the
neutron). He develops an equation for the energy of emission of
the atom (EM) in which M - atomic mass, Ey - energy of the gamma
quantum, m neutron mass, Q energy of nuclear reaction, c speed

germanium., iodine, antimony and arsenic. Table 3 shows (based
partly on data from a study of R. B. Duffield and A. Galvin f76,7
the holding for the gamma, n reaction and the n. gamma reaction in
in which such irradiating preparations as crystals of sa3-icylaldehyde-
ortho-phenylene diirdne and a solution of same in pyridine are applied.
It follows from Table 3 that, depending on irradiation conditions,,
a considerable part of radioactive atoms is hold in the form of the
original compound. F. S. Rowland and W. E. Libby (81) studied the
distribution of radioactive carbon originating from a reaction of
C12 (y. n) Cll between CO and C02 during irradiation of liquid and
solid carbon dioxide., solid NaHC03 and water solutions of NaHr-03
and Na2GO3-
Results of their tests are shown in Table 4 which shows that the
irradiation of solid samples leads to the condition that Cll is
evenly distributed between carbon monoxide and carbon dioxide.
However, the Rowland-Libby results do not agree with those of
Z. J. Sharman and K. J. McCallum (62) which are shown in Table 5
based on their study of the radiocarbon distribution obtained in the
irradiation by gamma-rays of sodiwa carbonate-,- W. J. Edwards and
K. J. McCallum (83) studied the chemical composition of C11 originating
with the irradiation of sodium bicarbonate and calcium bicarbonate by
gamma-rays with a maximum energy equivalent to 23 NeV. The samples were
irradiated for about 10 minutes under an intensity of gamma rays in the
range of 1000-2000 roentgens/minute; results are portrayed in Table 6.

of light, and 0 - the angle between the trajectories of the emitted
neutron and the indident photon, The energy of nuclei of emission
obtained in a gamma, n reaction is great aad exceeds by far the energy
of chemical bond of the atom in a molecule of any compound. The
interaction of heavy high energy particles with surrounding media
(solution,, crystals) and the concomitant chemical changes are of
great practical and scientific interest. The few studies made on
this subject can be classified under two groups; 1. studies on
enrichment of radioactive isotopes and 2. studies on the chemical
state (of atom) originating from the gam*,, n reaction. (The
author ~iveB-much detail under these groups; see explanation of
tables 2-6 below., and contributions of personalities).

TEXT: IaF 3 is twice precipitated from the solution to be analyzed which
contains the carrier Zr and the 44% HP (3ml). The precipitate is
separated, and the BaZrF6 is precipitated from the solution by mean:) of
saturated Ba(NO3)2 solution. The precipitate is centrifuged, washed with
0-5% HF and water, and dissolved by successive addition of 5 ml of 5~113BO3
solution, 10 ml of water, and 3 ml of concentrated HNO 3' BaSO4 is
precipitated by means of 5% H SO from the solution heated to boiling.

TITLE: The direct determination of calcium in plants, soils and milk
with use of a flame photometer
PERIODICAL: Zhurnal analiticheskoy khimii., v. 18, no. 4. April 1963, 440-443
TM Theauthors demonstrate experimentally that there is no lessening
of the intensity of radiation from calcium on account of quenchers (aluminum,
sulfate and phosphate ions), provided 8-hydroxyquinoline is present. On this
basis they suggest a method for the direct dcbermination of calcium in soils,
milk and plants, the removal of quenchers being unnecessary. There are 2 figures
and 2 tables. The most important English-language reference reads as follows:

TITLE: Heat TransferAhrough the Walls of the Spiral Cooler Under the
Conditions o? Bubbling
PERIODICALs Khimicheskaya promyshlennost', 1959, Nr 7, pp 622 - 624 (USSR)
ABSTRACTs The authors of this paper investigated the heat transfer on
absorption of sulfur trioxide in concentrated sulfuric acid
(98% H2304) for the preparation of standard oleum and on
absorption of sulfur dioxide in a solution of ammonium sulfite-
bisulfite. In both cases, cooling spirals were fixed to the
sieve plates of the absorption column. Table 1 shows the
characteristics of the apparatuses used and the working con-
ditions on investigation of the absorption of 30 and 502- .
The temperature of the cooling water was measurel when entering
and leaving the cooling spiral; moreoverp the consumption of
water (kg per hour) and the temperature of the bubbling layer
Card 1/3 at the plate were measured. This temperature was considered

to be constant at all points which corresponds to a complete
blending of the layer at the bubble plate. The heat transfer
coefficient K was computed from these values. The coefficients
of the heat transfer from the cooler wall to the cooling water
(cK2) and of the heat transfer,from the bubbling layer to the
wall of the cooling spiral (okl') were also computed. The respec-
tive equations are given in,the paper. Table 2 shows the results
of the experiments and computations. It 2appear that the values
of K are very high and reach 950 kca:L/M., our Since the I
heat trdnsfer,through the cooler walls u Pder Apvc-onditions of
bubbling is considerable, the same apparatus can also be used
for the cooling of hot liquids. In connection with it, the hot
liquid is conducted through t~e cooler; the bubbling layer is
cold. The evaluation of the obtained resul.ts showed thata~2
