TITLE: On the Fission of Nonspherical Nuclei (0 delenii nesfericheski"h yader) PERIODICIIL: Zhurnal eksperimentallnoy i teoreticheskoy fiziki, 1959, vol 36, Nr 3, pp 793-797 (USSR) A13STRACT: The bombardment of stable nuclei with fast particles may, if the excitation entergy of the compound nucleus is greater than the critical fission energy, lead to fission. In a non- spherical nucleus with rotational de:qree of freedom the centri- fugal force occurring in consequence of a rotation of the nucleus may lead to nuclear fission. The fission of a non- spherical nucleus caused by the abso:7ption of a particle with great momentum may occur directly without the intermediate stage of the formation of a compound nucleus. It may theoreti- cally also be treated as a direct fission process. In the present paper the author theorelically investigates this direct fission as a consequence of a transfer of a large , ular momentum of the nucleus by "he absorbed particle.

The present paper was intended to work out a theory of direct nuclear reactions (strippino reaction and deuteron formation) in which polarized particles participate; such reactions are widely used in nuclear spectroscopy. For their investigations the authors use the method of Derturbed waves; the spin-orbit interaction is neglected because it makes a comparatively small contri':.ution to the cross section. Also Coulomb effects are net-lected because they are insig- nificant in the case of sufficiently hiCh eneri-ies,, The paper deal's with a mathematical investiCation of the angular dis- tributiorl and polarization of the -' )roducts of stripl;ing- and Card 1/3 capture reactions during- the actio:-i of polarized particles On the Theory of Direct lNuclear Reactions dith SO'1/56-36-4-28/70 the Participation of Polarized Particles 'ion of pon arbitrarily oriented nuclei.

The formation of deuteron3 on nuclei by polarized protons is also characterized by the angular distribution -with azimuthal asymmetry, The deuterons produced on thhie --iccasion are polarized, The capture reaction under the influence of polarized nucleons can be neglected- in order to obtain polarized deuterons. The various chapters of this paper deal with the following subjects: The (d,p) strippina reaction with polarized particles. After the problein has been dealt with in a general manner, a special investiCation is carried out of three simple Card 2/3 cases: a) nucleus and deuterons are not polarized, b) the On the Theory of Direct Nuclear Reactions With SOV/56-36-4-28/70 the Participation of Polarized Particles nucleus is not polarized and deuterons are polarized, c) the nucleus is polarized and the deuterons are not. The next part deals with (d,p)- capturing reactions with polarized particles, Again the cases a,b, and c are deaLt with specially after a general investigation.. In the lasi; chapter the angular dis- tribution and the polarization of protons are finally calculated for the concrete case of the react-4on B11(d,p)B12 by using the given parameter values. The resul-;s obtained are shown by a diagram. The authors thank Yu. BerezhnV and V. Kharchenko for their help in carrying out numerical computations. There are 1 figure and 15 references.

The author of the present paper investigates (Tr,cl)-scattering; at high pion energies it is also d-iffraction scatter-Ing at which the shadow effects must be taken into account, the existence of which was pointed out for the first time by Glauber. The Card 1/2 investigation was carried out by `L-he author in accordance with On the Scattering of Past fr-Mesons on Deuterons sov/56-36-5-16/76 the method developed by Belenkiy. Expressions are given for the total-, the scattering-, and the absorption cross section, and further also for the corresponding angular distributions. The equations obtained are evaluated by means of experimental data in references I and 2 for Eir - 1.4 Bevq and results are shown by two diagrams. The integral (-q-,d) scattering cross section is found to be equal to the double elastic (Tr p) scattering cross section. In the (Tr1d) absorption cross section the shadow effect is distinctly marked. Figure 1 shows the course of angular distribution in the case of (Tr,p)-scattering and figure 2 shows that in the case of (irld) scattering. The author thanks A. I.

Such investigations furnish data on the dynamic properties of nuclei. There are two types of inelastic scattering; inelastic electron scattering may be accompanied by excitation of higher energy levels of the nucleus and furnishes data on the nuclear levels. On the other hand, it may also lead to an electrodisintegration (emission of protons or neutrons) and thus gives direct information on the momentum distribution of nucleons in the nucleus, which depends on their spatial correlation. These data are important to the further development of the theory of nuclear structure, especially for the mode of two-particle interaction between 'the nucleons.

The Introduction of the model collision integral makes it possible to investigate plasma fluctuations for an arbitrary value of the effective pair collision frequency. The article Investigates the case of a single-component, nontsothermal plaima. The fluctua- tion-dissipation relation is used to find a general expression for the correlation function of random forces. It Is shown that allowance for pair collisions between particles leads to an additional correlation of random forces In the velocity space. General formulas are obtained for the spectral distribu- tions of particle density fluctuations and temperature fluctuations. These formulas are used to investigate the effect of the magnitude oj! the effective pair collision frequency on the shapo of the spectrum of particle density and temperature fluctuations, from the collisionless case to hydrodynamics.

PERIODICAL lurn.eksp.i teor.fis,jl,fasc-5,905-907 (19~,6) Issued: 1 / 1957 Here the exterior electric field was used as a medium for the reversible modification of the surface charge. A monocrystalline Germanium plate (with soldered-on contacts for measuring the Hall effect and eonductivity) was pasted onto thin mica foils (30 to 50et) by means of polysterol varnish. A metal plate was pasted onto the reversed side of the inica foil. The Hall effect and conductivity were measured in the presence of an electric field(at + V and at - V on the metal plate) and also without such a field. From the re- sults of these measur ements the effective value of the mobility ue was de- termined. The results of these computations are shown for some samples in a table. Measurements were repeated several times and were found to be absolu- tely reproducible. Under the effect of the exterior electric field the resistances of the simples with electronic as well as with own conductivity increased at + V and di- minished at - V on the metal plate. Also Hall's electrcmotoric force V x and the mobility ue were measured. At -V on the metal plate they increased and at +V they diminished. If a surface zone of electric condt.otivity exists, the mo- bility of the electrons on the surface is lower than in the interior of the sample LYASHENKO, V.I. [Liashenko, M.]; SITENKO. TAT.

TITLE: Effect of the surface condition on the Hall effect and the magnetic resistance of germanium PERIODICAL: Fizika tverdogo tela, v. 3, no. 4, 1961, '079-1084 TEXT: It has been shown by the authors in earlier papers that the Hall effect and the magnetic resistance depend essentially on the condition of the surface of a semiconductor. The mechanism of the scattering of excess carriers is important for the interpretation of a number of surface- sensitivity effects. Therefore, the authors carried out further investiga- tions of these effects for different treatments of the surface and are reporting on the results in the present paper. The samples were cut from, a p-type Ge single crystal; they had a resistivity 42 ohm.cm and L, volume lifetime 300 Psec. After etching with C-'~'-4 (SR-4) they had a size of 0.4s 1-0~ 0.017 cm (12-1) and 0.4x 1.?A 0.0165 cm (11-I). The measurements were made at a constant temperature, (+ 20.5 + 0-5)oc, in the field of 3000 oe, and at a pressure of 10-6 mm Hg 15 se7c after the Card 1/6 :!

The maximum of the Hall con- stant nearly coincided with the minimum of conductivity. The results obtained proved to be well reproducible. By a short action of an electric field only the filling of the surface states was altered. To influence the energetic structure of the surface, samples 11-I and 12-1 were etched once more in boilin;, H 0,, but no essential chcn-es occurred.

Ye. Pikus (ZhTF, XXVI, 22, 1956). Results of the comparison are shown in Figs. 2 and 3- It is seen that a consideration of the light holes slightly improves the agreement between theory (Pe.tritz, Zemel) and experiment. The authors carried out the calculations for light holes of the following parameters: r = 2.25-10- 2 , b - 7-5 (r is the concentration and b the mobility ratio of light and heavy holes). The theory of Petritz and Zemel is discussed in detail. The comparison of the results with the theory of Pikus showed that the effect of surface recombination on Z-\?/OH2was insignificant under the present experimental conditions. It was found further that the different chE.racter of the dependence of 6?/Y on the external electric field for two different orientations of the sample in the magnetic field at t continued to exist even in the absence of any band curvature.
