Comprehensive experimental and theoretical study of: electronic excitation of subvalent shells of atoms and metal ions by slow electrons; spectra and mechanisms of excitation of emissions in the ultraviolet and visible regions in the plasma of inert gas discharges with a vapor of biological molecules; the influence of nuclear shells on the formation of mass distributions of nuclear fission fragments with Z=80–90, mechanisms, excitation channels and disintegration of 232Th states; influence of electromagnetic and corpuscular radiation on the processes of formation of nanocrystalline inclusions in thin-film structures and their phase equilibria; theoretical study of the interaction of electrons and mesons with atoms and molecules, field equations for particles with arbitrary mass and spins 3/2 and 2. To provide research used our own original developments: monochromators and energy analyzers of high resolution electrons, sources of beams of atoms and ions metals with high evaporation temperatures and high chemical activity, as well as a series of devices for generating discharge plasma of inert gases in mixtures with amino acid vapor. The structure of the energy loss spectra of primary and ejected electrons of lithium and sodium atoms has been studied, and AIS decay channels have been established. It is determined that the main mechanism of electronic excitation of satellites of ion spectral lines is dielectron recombination. In the luminescence spectra of plasma jets, the presence of radiation of nitrogen molecules and their positive ions in argon-air and helium-air mixtures was established. The optimal parameters of the stimulation schemes of excitation reactions of complex nuclear systems on the M-30 microtron have been established.
