金等离子体M带谱3d→4f和3d→5f电子离子碰撞激发强度

Theoretical study on electron impact excitation of Au^(51+)、Au^(50+) and Au^(49+) ions

电子离子碰撞激发强度在超组态碰撞辐射模型中真实模拟非局域热动平衡金激光等离子体M带谱跃迁中离子的平均电离度、电荷态分布和能级布居数等离子的电离态特性是必不可少的.基于全相对论扭曲波电子碰撞激发计算程序REIE06,系统计算了高离化态金离子(Au51+、Au50+、Au49+)精细结构能级3d→4f和3d→5f的碰撞强度,计算中详细考虑了电子关联效应和Breit相互作用对碰撞强度的影响.计算结果与可获得的其它理论及实验结果进行了比较,取得了好的一致性.

The electron impact excitation （EIE） collision strengths of Au5l＋,Au50＋ and Au49＋ ions are calculated systematically by using the fully relativistic distorted-wave program REIE06.The EIE collision strengths versus different energies of incident electron are studied,and some important conclusions are summarized.In the calculations,the relativistic effects,the electron correlation effects and the effects of the Breit interaction are considered systematically.Also,comparisons of the present calculations with the available other calculations and experimental results are made.
