摘要: 采用Coulomb-Born交换近似,在Z标度类氢模型下计处了‘水窗’波段Mn22+离子精细结构能级的电子碰撞激发截面和速率系数。为了更有效地考虑碰撞过程中电子的关联和相对论效应,在计算中对有效核电荷的计算作了修改。

关键词: 水窗, 有效核电荷, 精细结构能级, 截面, 速率系数

Abstract: By using Coulomb-Born-exchange approximation and Zscaled hydrogenic approximation the excitation cross sections and rate coefficients between fine-structure levels of Mn22+ in water window are calculated.In order to take the correlation effects and relativistic effects into account more effectively, the effective nuclear charges are modified in the computation.

Key words: water window, effective nuclear charge, fine-structure level, cross section, rate coefficient
