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 Mn^(22+)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。
By using Coulomb-Born-exchange approximation and Z-scaled hydrogenic approximation the excitation cross sections and rate coefficients between fine-structure levels of Mn^(22+)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.
