摘要: 利用扭曲波方法计算类He离子的电子碰撞激发截面。靶波函数采用HFS自洽场波函数,本文计算了若干元素从基态(11S)到21S,21P,23S,23P的跃迁。计算结果以碰撞强度的形式给出。入射电子能量从激发阈能开始到x=10,计算结果与已有的结果作了比较,分析表明,在大多数情况下,结果是满意的。

Abstract: The electron impact excitation of He-like ions is studied by distorted wave method. The HFS wave functions of the target are used. We have calculated the transitions between the 11S and 21,3S, 21,3P states for some He-like ions. Results are presented in terms of collision strengths. The incident electron energies are from threshold to x=10. The results are compared with the data avaible. It is shown that the results are satisfied in most cases.

Key words: excitation, collision strength, distorted wave, cross section
