Closed model of Universe on the earlier stage of its evolution is defined more precisely. It is considered here that after the Big Bang and De Sitter’s (exponential) expanding phase in which the pressure is p=-c²ρc (see ...

The estimation of contribution of the second Born approximation into circular polarization of bremsstrahlung from linearly polarized electrons is obtained. Account of this contribution could be important for correct ...

Simple variant of eikonal approximation in transition radiation theory is proposed. Spectral-angular density of radiation on fiber-like targets and nanotubes is calculated using Born and eikonal approximations. The conditions ...

The equations of motion of electrons in a plane monochromatic wave with linear, circular and elliptical polarizations are solved taking into account the initial conditions. The cases when the interaction of the electrons ...

The new perturbation theory in QED without the ultraviolet catastrophe is constructed.

Radiative corrections (RC) to the differential and total Compton scattering cross sections are calculated. We consider the scattering of photon with a few GeV energy by the atomic electron. The reason is the unique possibility ...

We present, for general relativistic case, a theoretical investigation of the resonant two-photon emission of an electron in the circularly-polarized electromagnetic wave. Resonances are related to a virtual intermediate ...
