Elementary Processes in Gases and Plasmas
Elementary processes involving atoms, electrons and ions are analyzed. Peculiarities of cross sections and rate constants as characteristics of these processes are considered. Various pair and three body collision processes are considered as elastic electron-atom scattering, processes of excitation, quenching and ionization of atoms by electron impact, elastic scattering and resonant charge exchange for ion-atom collisions, atom ionization in collisions involving excited atoms, electron-ion recombination and electron attachment to molecules. Physics of these processes is analyzed and numerical parameters of their cross sections or rate constants are given. Additionally processes are represented in an excited or ionized air. The character of elastic electron-atom collisions including the Ramsauer effect is represented within the framework of the phase theory of scattering.
