摘要 在相对论框架下 ,给出了电子与高电荷态离子碰撞直接电离截面的扭曲波玻恩交换近似计算方法 .作为示例 ,计算了几个离子 (类氢、类锂和类氖离子 )的电离截面 ,计算结果与实验值和其它理论计算值有比较好的符合 . A fully relativistic distorted-wave exchange approximation method is presented. It can be used to obtain electron impact ionization cross section of highly charged ions. The ionization cross sections of several H-, Li, and Ne-like ions have been calculated. Good agreement is obtained while the calculated values are compared with the experiments or other relativistic calculations.
