Ionic recombination in a weakly ionized gas

Abstract: Using the framework of a stochastic approach to the reaction-kinetic problem originating from Teramoto and Shigesada equations for the phase-space evolution of the ionic part in a diluted ternary gas mixture composed of positively and negatively charged ions as well as of neutrals are derived. On the basis of the stationary solution of the reactive ion-pair equation an operator expression for the recombination constant α is defined and discussed with regard to the effect of the center-of-mass motion. By iteration a formally exact α-expansion in terms of multiple ion-pair neutral collisions is derived for the case that non-thermal center-of-mass effects can be neglected. This expansion has to be specified to meet the conditions of well-known models for ion-pair stabilization (absorbing sphere, critical energy barrier).
