Screening effects on resonant charge-exchange collisions in strong coupled plasmas

Plasmas screening effects on the resonant charge-exchange processes by stripped ions from hydrogenic ions in strongly coupled plasmas are investigated using the ion-sphere model. The semiclassical straight-line trajectory analysis is applied to describe the dynamic behavior of the collision system. The plasma screening effects on the resonant charge-exchange probability in strongly coupled plasmas are found to be decreased with increasing ion sphere radius and collision energy. It is found that the maximum position of the resonant charge-exchange probability is receded from target nucleus with a decrease of the ion-sphere radius and however is almost unchanged with increasing collision energy.
