类锂离子C^（3＋）的电子碰撞电离

Electron Impact Ionisation of Li-Iike ion

采用扭曲库仑波函数描述碰撞电子，用Ｒ－矩阵密耦波函数处理被电离电子与剩余离子构成的系统初末态，在库仑－玻恩各级近似下计算类理离子Ｃ￣（３＋）的电子碰撞电离截面及相应速率系数。所得结果与Ｊａｋｕｂｏｗｉｃｚ的结果相一致。

By means of distorted coulomb wavefunctions to describe an ionising electron,and R-ma-trix basis to expand both the initial target state as well as the continuum state consisting of the finalelectron ion and ejectecd electron,the electron impact ionisation cross section of Li-like ion C￣(3+) andthe corresponding ionisation rate coefficients have been calculated, for the first time,within theConlomb-Born approximations and five-state close-coupling approximation.
