[en] The subcritical modes of operation of the BN-600 reactor driven by proton accelerator are investigated. It is shown that the creation of sufficiently economical and safe power plant on the base of such type system is quite real at the existing level of the accelerator technique. 11 refs

[en] As is shown, the influence of induction effects on the development of beam-plasma instability is the coupling coefficient between the beam and plasma is small. In such a case, there arise a seft-congruent, longitudinally homogeneous electric field, which accelerates the beam electrons. The induction effects lead to the prolongation of linear stage of instability development and some increase in the maximum amplitude of the field of plasma oscillations. 7 refs

[en] The Rayleigh and combinational scatterings on a two-level atom in a homogeneous gaseous medium are considered in two limiting cases when analytical solutions are possible. Analytical expressions for the corresponding probabilities of the Rayleigh and combinational scatterings are obtained for the case of non-stationary switching on of the interaction. 9 refs

[en] The integrability of the three-level quantum-mechanical problem in terms of generalized hypergeometric functions 2F2 is studied. A total of 4 infinite classes of models integrable in terms of these functions is derived one of which is a generalization of the previously known subfamily, and the others are new

[en] A method for finding the wave function of an electron infinitely moving in the field of an arbitrary layered structure bordered on both sides with two different semi infinite media is proposed. It is shown that this problem in the general form can be reduced to the solution of some system of linear finite-difference equations. The proposed approach is discussed in detail for the case of a periodic structure

[en] The nonlinear absorption of light in many-layer size-quantized heterostructures in considered, taking into account the screening of Coulomb interaction of electrons and holes by nonequilibrium carriers. Calculations for the Elliot factor are given and some features of saturation effect in size-quantized structures are discussed. 6 refs

[en] The magnetization of lithium niobate crystal doped with iron, nickel and copper ions under the action of pulsed ruby laser is investigated. Plots of e.m.f. signals against laser pulse intensity, polarization and direction of optical radiation, propagation, the kind and concentration of impurity ions were obtained. Estimates of time, pulse height and polarization show that the mechanism of the rise of e.m.f. in doped lithium niobate crystal is its magnetization. 9 refs
