摘要
采用我们的“快速”扭曲波方法和程序MCDW(9),计算了类氖Ce^(22+)27个精细能级之间351个过程的激发截面,并且与其它理论值进行了比较.结果表明:碰撞强度大的过程一般符合在10%左右.但是由于组态混合导致跃迁矩阵元严重抵消而变成为相对小的过程以及激发能很小的光学禁戒(电偶极振子强度为零)过程,其截面(或碰撞强度)对模型细节敏感,不同作者计算差别较大.
With our rapid multi-configuration distorted wave (MCDW) method and corresponding code MCDW(9), the excitation cross sections of Ge22+ ion by electron impact have been calculated. All the 351 transitions between 27 fine structure le-vlels of Ge22+ ion were investigated. The cross sections with large values agree with other theoretical results within 10%. For some of the cross sections with small values, and for optical forbidden transitions with small excitation energies, a relatively large discrepancy exists.
