类氢离子电子碰撞电离截面的扭曲波计算

DISTORTED WAVE CALCULATIONS OF ELECTRON-IMPACT IONIZATION CROSS SECTIONS FOR H-lIKE IONS

在扭曲波库仑玻恩交换似近下用编制的计算程序计算了类氢离子Ｈｅ，Ｃ，Ｎｅ，Ｓｉ，Ｃａ，Ｆｅ的电子碰撞电离截面，并将结果与Ｙｏｕｎｇｅｒ的扭曲波结果作了比较。在２％以内本文的结果与Ｙｏｕｎｇｅｒ的结果一致。

The electron-impact ionization cross sections for H-like ions He,C,Ne,Si,Ca and F e were calculated with the distorted wave Born exchange approximation.The results were compared with the S.M.Younger's ones.The excellent agreement was obtained with a error of 2%.The effects of semi-empirical exchange potential on the cross sections were also investigated in detail.
