A series of scientific works  consists of 1 monograph, 1 chapter in the book of foreign publishing, and 11 scientific articles published during the eight years.


Fundamentals of the theory of relativistic effects of the strong external light field on general processes of quantum electrodynamics were developed.

Series of fundamental results were obtained, namely, processes of the second order in the fine-structure constant in the pulsed light field (bremsstrahlung of an electron scattered by a nucleus, photoproduction of an electron-positron pair on a nucleus, scattering of an electron by a muon, the Compton effect) had been first studied theoretically. It was ascertained that resonant cross sections of these processes exceed considerably corresponding cross sections in the external field absence. The effect of anomalous amplification of the laser field in scattering of a nonrelativistic electron in the field of the moderately strong wave of arbitrary polarization was first revealed.

The scientific innovation consists in accounting of the pulsed nature of the external field and studying of the new regularities and effects that arises here. The approximation of the quasimonochromatic wave, if the number of field oscillation during the pulse width is large, is considered.

The results of the series of scientific works are important for solving the problem of experimental verification of quantum electrodynamics in the strong fields.
