摘　　要：考虑了内壳层电子激发的组态相互作用后，采用Ｒ矩阵方法计算了电子碰撞类锂碳离子的共振激发碰撞强度。对于１ｓ２ｓ２Ｓ－１ｓ２ｐ２Ｐｏ跃迁，结果介于密耦方法和Ｃｏｕｌｏｍｂ－Ｂｏｒｎ交换近似结果之间。The R matrix approximation is used to compute the excitation collision strength of electron impact on Li like C with the configuration interaction wavefunctions, in which the configuration interactions of an inner shell electron excitation are included. For transition 1s 22s 2 S 1s 12p 2 P o, the result in this paper is a little smaller than that of the close coupling approximation and a little larger than that of Coulomb Born exchange approximation,and accords with that of the experiment except that nearer excitation threshold.
