摘要
利用局域场修正的介电函数,研究了注入离子在强耦合简并电子气中的阻止本领和能量离散。数值结果表明在低速和高r_s值情况下,局域场修正使得阻止本领和能量离散明显地增加。
The stopping powers and energy stragglings for implanted ions in strongly coupled degenerate electron gas were investigated using local -field correction dielectric function .The numerical results have shown thst the stopping powers and energy stragglings were considerably increased due to local -field correction at low volecities and high valuse rs.
