The processes of electron excitation, ionization (including excitation-autoionization) of the subvalence shells of the Rb, Sr, Ba atoms and Zn+, Tl+ ions, as well as the dielectronic recombination of the Tl+ ion were investigated for the first time; the autoionization cross sections for the excitation of the subvalence shells of the Rb atom and the integral and differential cross sections of electron scattering at the Zn and In atoms and ions, as well as at the SFn (n = 1,2,4,6) sulfur fluoride molecules were calculated. Energy and dynamic characteristics (effective cross sections, channels of the excited states formation and decay, spectroscopic classification of excited states of atoms and ions) were obtained. The role of resonant and autoionization phenomena in the processes of excitation-autoionization, excitation and dielectronic recombination is established to increase with the complication of the structure of electron shells of atomic systems. Multielectron effects due to the inter-shell interaction between valence and sub-valence shells play the main role in this case. Product Description popup.authors popup.nrat_date 2020-04-02 Close
