Charge kinetics in weakly ionized plasma of electronegative gases

This work is devoted to investigation of specific features for processes of ionization and recombination in a weakly ionized plasma of electronegative gases in an external electric field in the presence of ion-molecular reactions. By analogy with the problem of the shift of the energy level of the ground state of the quantum-mechanical Fermi system, a simple analytic expression for the calculation of the effective ionization rate under these conditions was found. For the first time, a criterion of the dielectric strength for electronegative gases, which takes into account all the ion-molecular reactions with the participation of negative ions, is formulated. The recombination process in the ion plasma of electronegative gases is considered both in the presence of and without these reactions. Cases permitting the analytic solution of a set of differential balance equation for components of the decaying ion plasma are selected.
