Plasma screening effects on resonant charge transfer in strongly coupled plasmas

Abstract

The resonant charge transfer process in collisions between positive ions has been investigated in strongly coupled plasmas. The ion-sphere model is applied to describe the interaction potential in strongly coupled plasmas. The electron transfer probability and the electron transfer cross-section are obtained as functions of the energies of the symmetric and antisymmetric states, ion-sphere radius, and collision energy. The results show that the plasma screening effects enhance the resonant electron transfer probability as well as the electron transfer cross-section in strongly coupled plasmas.
