The object of research is nonequilibrium, spatially inhomogeneous systems of condensed media under powerful nuclear and electromagnetic radiation. The aims of the research are to calculate the physical parameters of condensed matter under powerful nuclear and electromagnetic radiation, to explain scientific experiments performed at the institutes of the NAS of Ukraine, and to search for new effects promising for application. Research methods are the modern methods of theoretical physics. Among the most important results we note: 1) studied the possibility of excitation of 8.3 eV lasers 229mTh isomer in an electronic bridge through a continuous spectrum, 2) explained the existence of two types of self-oscillations in electron-irradiated methane at low temperatures and determined their properties; 3) for the first time explained and analyzed the structure in thermoluminescence, which is caused by molecular oscillations of quantum energies resonant to the depths of defective levels; 4) studied and analyzed the solutions of the equation of the velocity characteristics of the traveling wave of divisions / reactor CANDLE: the relationship between reactivity, reactor power and control parameters of the reactor model is obtained; 5) the reason for the increase in the neutron flux density in the Shelter object is analyzed and it is shown that the amplitude of such a burst should not exceed the amplitude of the primary oscillatory process that took place in 1990; 6) studied light-controlled exciton pulse generator in semiconductors; 7) calculated spectra of excitons and the possibility of their condensation on macroscopic defects on the surface of the quantum well, which occur in places of narrowing or widening of the quantum well; 8) the previously proposed model for calculating the positions of exciton bands in double semimagnetic wells based on Cd0.95Mn0.05Te/CdTe heterojunctions is used to describe the results of experiment Product Description popup.authors Anokhin Igor Ye Vertsimakha Ganna Vitaliyivna Goliney Igor Yu Dzyublik Olexiy Ya Mykhaylovskyy Vitaliy V Onykiienko Yehor V Pavlovych Volodymyr M Ryazanov Vasily Vasylyovych Spivak Volodymyr Yurijovych Fishchuk Ivan I Chernyuk Andriy A popup.nrat_date 2022-03-09 Close
