Slowing down for Ion Penetration through Plasmas

Abstract

Slowing down processes for a proton and a carbon ion penetration through plasmas are studied within the dielectric response theory.The results show that the stopping power of ion will increase in lower projectile velocity, while the value of stopping power will decrease for higer velocity, and there is a maximum value for stopping power for some projectile velocity due to the resonace of excitation of plasmas. In addition, the stopping power will have higher value for carbon ion than proton due to the effects of charge states. Introduction
