[en] Ultrasound effect on the dynamic diffraction of Moessbauer gamma quanta in a silicon monocrystal is studied. Complete intensity and its elastic part for (111), (333), (444) and (22-bar0), (4-bar40) reflexes are measured in the Bragg geometry under effect of high-frequency US (transverse waves). A reduction and oscillation of elastic scattering intensity are observed with US amplitude growth which contradicts the results of the previous works (1,2). 4 refs., 2 figs

[en] The version of a trap. wherein particles move in a homogeneous constant magnetic field and electrostatic field, formed by two equipotential planes and rotation axial surface, is proposed. The solution of canonic equations is found. It is shown that interaction of electrons with the radiation field leads to damping parametric resonance. The trap model, accounting for the finite conductivity of the resonator walls and losses by collisions with gas, is studied

[en] The new physical scheme of the source of the Bremsstrahlung x-ray and γ-radiation wherein the process of the photon emission is accompanied by electrons acceleration, is discussed. The above scheme significantly increases the yield of both soft and hard photons by retaining compact dimensions of the whole device. The computer modeling confirms high efficiency of such a system

[en] The totality of experiments for the model-independent determination of amplitudes of the atoms autoionization states excitation through an electron shock by the ²S → ²L transitions in a single-electron atom is proposed. It is shown that complete experience for determining the autoionization state excitation amplitudes requires three measurement stages. Taking into account the experimental studies state in the electron-atom collisions physics, these measurements seem to be presently impossible

[en] The full radiation power of the classical neutral particle, having anomalous magnetic and electrical moments, by its motion in an arbitrary electromagnetic field is identified. The result is obtained under the assumption, that the particle spin evolution is determined by the Bargeman-Michel-Telegdi generalized equation

[en] The dynamic of formation of the wolfram light β⁺ radioactive isotopes under the effect of the Bremsstrahlung radiation beams of various intensity with photon energy, corresponding to the excitation of the dipole giant resonance is studied. The hypothesis on the possibility of formation of the elements most light stable isotopes under the effect of the γ-quanta high-intensity flows is proposed

[en] General formulae for frequencies, intensities and phase factors of two-dimensional spectra of the first order in the nuclear magnetic resonance correlation spectroscopy, corresponding to the (π/2)_x - t₁ - (π/2)_x - t₂ pulse process. Are derived using the projection operator method. 4 refs

[en] Features of local iron and aluminium atom distributions in β-Mn_2.75Fe_0.25Al after different types of heat treatment are ascertained as a result of a complex x-ray and Moessbauer investigation. 13 refs., 1 fig., 1 tab

[en] One-loop radiative shift of electron energy in the ground state in the magnetic field within the (2 + 1)-dimensional quantum electrodynamics, the Lagrangian whereof includes the Cherna-Simons member of topological nature, is calculated. Asymptotic behaviour of the energy shift as the function of the field intensity and topological mass parameter is studied

[en] The spectrum and width of the b → s + γ decay in the external non-Abelian chromomagnetic field, modelling vacuum gluon condensate are calculated. The result obtained correlates with typical non-perturbative corrections, calculated earlier through other methods. It is shown that the gluon condensate effect consists in the quark weighting and chromomagnetic moment interaction with chromomagnetic moment interaction with chromomagnetic field
