Purpose of the work - theoretical comprehension and description of the fundamental regularities inherent in the physical processes in the systems under investigation. Methods of the investigation - relativistic theoretical methods of the investigation of quantum-electrodynamics processes in strong external fields, generalized optical model of nucleon-nucleus interactions, thermodynamic theory of phase transitions, data treatment by using the wavelet analysis and contemporary spectral methods, ellipsometric method. Results of the investigation and their novelty: the nonlinear quantum electrodynamics processes in the strong external fields of various nature are investigated; the influence of tensor nucleon-nucleon forces on the nucleon-nucleus optical potential is studied; the high-frequency properties of anti ferromagnetic materials in the phase transition vicinity are investigated; the new approach for the treatment of light ions backscattering spectra is proposed; the new method of analysis of positron life time spectra is proposed; the analysis of ellipsometric incorrect reverse problem is carried out for the case of super thin surface films, the new criteria of the optimal point choice are proposed and the stable solution of the ellipsometric reverse problem is found Product Description popup.authors popup.nrat_date 2020-04-02 Close
