用自编的扭曲波程序ＡＣＤＷ（９）和拟合程序ＦＩＴ（９），计算了一系列类锂离子的碰撞激发过程．找出了约化碰撞强度Ωｒｅｄ是约化电子能量εｒｅｄ的慢变函数，约化速率系数因子γｒｅｄ是约化电子温度Ｔｒｅｄ的慢变函数．对某种离子的一个激发过程，可用１０个参数描述，由这１０个参数可以得到任意电子能量下的碰撞强度和激发截面，以及任意温度下的速率系数The collision strengths of excitation by electron impact from nl to n′l′ with n(n′)≤7 of Li-like ions are computed systematically. The results agree with available data within 10%. The collision strengths are scaled and fitted with a least-squre spline method. As a result, the collision strengths and thermally averaged rate coefficients in the entire range can be determined by ten parameters for one transition process.
