The layers of uranium oxide (with 97,8 % U235) vore deposited electrolytically on the electrodes of the chamber.

The distributions of the impulses on the amplitudes obtained by these measurements are shown in a dizL6-ram. The spectra have the same shape within the ranoe of amplitudes investigated. In the fission of U255 by thermal neutrons this range of amplitudes covers about goiTa' of the total amount and 65-7o~', of the total amount of momentary quanta.

L?xperimentally it was found that for the u235 fission by thermal neutrons and by 2.8 and 14.7 Mev neutrons the values obtained for the total y-energy within the limits of + 15% coincide (Ref 3). The purpose of the present paper (III7etter to the Editor ") was to obtain data concerning the division of energy by y-rays in U238- fission by fast neutrons. The same method and apparatus were used as in the case of reference 3; the I-spectra of U238- fission by fast neutrons and those of U235-fission by thermal Card 1/3 neutrons were compared; 7-counting was carried out by means Y-Rayn, Accompanying U238 Firsion by Neutrons of the SOV/56-36-3-63/71 Eneroy 2.8 and 14.7 Mev of a scintillation counter with NaJ(Tl) crystal connected in coincidence with a single-layer fission chamber. The chamber contained, with conditions otherwise being the sa-ne, a U235- target (1.6 mg/CM2) and also a U238-target (2.2 mg/cm2). The results obtained by these investigations are shown by a diagram showing the dependence of the ratio coincidence/ fissions on the impulse amplitude in v. Measuring values are along a straight line which declines in the direction of growing amplitudes. The ratio of coincidences between I- quanta and fragments in the case of U238-fission by 2.8 and 14-7 Mev neutrons and the number of coincidenceain the case of U235-fission by thermal neutrons is given as amounting to 1.03+0.03 and 1.00+ 0.02 respectively. The authors again arriVe at the conc-lusion that for U238-fission by 2.8 and 14.7 Mev neutrons the average total energy of y-quanta agrees up to + 15,14 with the values obtained for ~235_fission by thermal ne7u-trons.

TITLE: Determination of the mean lifetime of excited states of U235 fission fragments PERIODICAL: Izvestiya Akademii nauk SSSR. Seriya fizicheakaya, v. 25, no. 1, 1961, 143-144 TEXT; The mean lifetime of excited states with respect to the emission of gamma quanta has been determined by measuring the solid angles cal- culated from excited fragments. According to V. V. Sklyarevskiy, D. Ye. Fomenko, Ye. P. Stepanov (Ref. 2), the main fraction of gamma radiation corresponds to a fragment lifetime of (0-5 - 2-5)*10-9 see. The afore- mentioned authors, as well as A. B. Smith, P. R. Fields, and A. Mo Friedman have come to the conclusion that the emission has, above all, a dipole character. The ionization chamber shown in the accompanying figure was placed in a current of thermal neutronu. The coinciding pulses originating from gamma quanta and ionization chamber were determined. When the distance between the layer of fissile material and the Card 1/4 Determination of the mean lifetime ... S/048/61/025/001/026/031 B029/BO63 collecting electrode of the ionization chamber is increased, the number of coincidences decreases owing to the emission of gamma quanta from fragments traveling over a large distance, i.e., owing to the decrease of the solid angle calculated from the fragments to the crystal. The decrease occurs during the emission of gamma quanta from fragments. The relation - 12N _ L = %N Y5 !Q)/vf(r) holds for the mean lifetime. f(r) is a function of the distance between the layer of fissile material and the collecting electrode of the ionization chamber; N is the number of coincidences corresponding to one fission event; N I is the number of gamma quanta emitted in one fission event; f is the efficiency of the gamma counter; v is the mean fragment velocity; and Q is the solid angle calculated from the layer of fissile material to the gamma counter. The gamma quanta were recorded by a scintillation counter with an NaI(Tl) crystal, and the fragments were counted by a single-layer ionization chamber. A layer of uranium oxide with 97.6;.o, U235 was applied to the chamber bottom by means of an Card 214 81"60, -----Determination of the mean lifetime 8/048/61 025/001/626/031 B02~/B% Ai backing.

This value Is in good agreement with the results obtained by other methods. According to this experimental lifetime, the gamma quanta are chief'ly emitted from excited fragments after evaporation of neutrons. Since several facts contradict the usually accepted theory of neutron evaporationt a search for shorter emission periods of gamma quanta during fission would be of particular interest, A, X.

Seriya fiziki i khimii, 1959P Nr 2, pp 152-155 (USSR) ABs,rRACTs The co-precipitation proved to be one of the most promising enrichment or concentration methods of separating thallium from materials with a very low oontent of thallium. Poorly soluble metal iodides are used as collectors for the thallium. Similar investigations with copper and silver iodides are indicated in publioations (Refs 1-2). Investigations with copper and mercury iodides have not yet been carried out. This method tested in this paper with the monovalent metal iodides of the mentioned metals# proved to be particularly suitable for investigations of mercury-containing materials on one hand; on the other hand, the presence of copper does not disturb the final determination of thallium by tho colorizetrio methyl violetzethod. In order to prevent the formation of free iodine in the copper iodide Card 1/3 solution, the presence of which disturbs the precipitation of Co-precipitation of Thallium With Copper and SOV/54-59-2-23/24 Mercury Iodides thallium, a reducer was introduced In the form of fresh-made sulphuric acid. To investigate the optimum conditions for a complete precipitation of thalliumt the copper iodide content and the VH-value of the solution were varied in a solution volume of 25 al at 180 and a thallium content of 501w Th. The results of this investigation are compiled in a table. The optimum conditions were attained at a pH-value of 2.9 and a thallium-copper ratio of It200, At an increase in temperaturej, the precipitation of thallium became worse. Investigations with thinner solutions also yielded worse results. The precipitation mechanism is considered as a surface adsorption of the thallium on the copper iodide. Besides, the thallium is determined In some natural compounds by means of this method, For the precipitation of thallium, with mercury iodide, an excess of potassium iodide had to be introduced to stabilize the Hr-J in this way, it was possible to precipitate 95% 2 2; of the thallium from 20 ml of solution (0.001 mol/l KJ excess) with 254- thallium at a pH-valus of 3.3 - 4 and a mercury- Card 2/3 thallium ratio of 111300- A further excess in KJ reduced the Co-precipitation of Thallium With Copper and BOV/54-59-2-23/24 Mercury Iodides yield. Toots with a boiling solution yielded worse results. The precipitation mechanism H92J2 - Th is also considered as a surface adsorption. There are 1 table and 5 Soviet references.
