利用扭曲波玻恩交换近似,计算了类锂离子的电子碰撞激发-自电离截面和总电离截面,与紧耦合计算及实验数据比较,得到了比较令人满意的结果。同时给出计算各种离子内层激发截面的一般公式。The cross section of inner-shell excitation followed by auto-ionization and total ionization cross section of lithium-like ions by electron impact have been calculated by using a distorted wave Born exchange approximation. The comparison of present data with close-coupling calculation and experimental measurement is satisfactory.
