AbstractAbstract
[en] Based on the analysis of dependence of complete cross sections of light nucleus photodisintegration on gamma quantum energy in the intermediate energy region and of energy and angular correlations, differential cross sections of reaction products in C.M.S. a conclusion is drawn that electric dipole gamma quantum absorption by correlated neutron-proton nucleus pairs appears to be the basic mechanism of light nucleus photoabsorption reactions with the production of nucleon-nucleon pairs. 26 refs.; 3 figs

AbstractAbstract
[en] The process of relativistic electron and positron scattering on nuclei in a thin silicon crystal is investigated by computer simulation using a binary collision model. Oscillations of nuclear collision probability and mean-square scattering angle are detected. A good correlation between probability and mean square scattering angle oscillations is observed. Calculations are prefromed under scattering in a plane (100) channel and scattering by a disorineted target

AbstractAbstract
[en] Asymmetry of cross sections of inclusive γ6Li → px process for proton escape angle of 90 deg in l.s. at 60, 140, 300 MeV photon energies is measured on a beam of lineraly polarized monochromatic photons. A notable asymmetry, its energy dependence being qualitatively in line with energy dependence of γd → pn reaction asymmetry is detected

AbstractAbstract
[en] Recently irradiated ammonia has been widely used as a working material of polarized targets. Methods for producing high polarization of deuterons in irraiated ammonia (ND3) are presented. Using the methods described maximum polarization values p+=35% and p-=39% are obtained in 2.6 T field at T=0.2 K

AbstractAbstract
[en] Comparison of probability flow and transition probability into a unit of time in the problem related to particle extraction from a potential well in a constant electric field is conducted; it is shown that these values differ sufficiently from each other. In case of a weak electric field quantum particle transfers from a quasistationary level in a continuous spectrum state, which lead to the non-exponential disintegration law, appear to be the main mechanism of bound state decay
