To achieve the goal, you need to complete the following basic tasks: • study of excitation processes, elastic scattering, ionization, dissociative ionization and formation of negative ions of complex molecules under the action of monokinetical electrons; establishment of appearance energy of ionized fragments of dissociation of these molecules; • study of the energy structure of the molecules and its transformation by investigation of luminescence spectra when irradiated by laser, UV, X -ray and high -energy (more than 10 MeV) radiation (photons, electrons, neutrons); • study of the spectral characteristics of amino acids molecules by investigation absorption and luminescence spectra; • study of physicochemical processes in low-temperature plasma in a gas vapor pair of sulfur, selenium and telur of longitudinal pulse-periodic discharge of low pressure and high pressure barrier discharge; • study of the emission properties of low-temperature plasma on a vapor of atoms, molecules, clusters of chalcogen and their ions; • development of gas discharge sources based on chalcogens with optimal spectral, energy and time characteristics. popup.nrat_date 2024-12-09 Close
