低能电子与类锂碳离子碰撞的共振激发
-
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1s22s2s-1s22p2p跃迁，结果介于密耦方法和Coulomb-Born交换近似结果之间，而且除了紧靠近激发阈值的 能量区域外与实验结果符合。Abstract: The R matrix approximation is used to compute the excitation collision strength of electron impact on Lilike C with the configuration interaction wavefunctions, in which the configuration inte ractions of an innershell electron excitation are included. For transition 1s ２２s２S１s１２p２Po,the result in this paper is a litt le smaller than that of the close coupling approximation and a little larger than that of CoulombBornexchange approximation，and accords with that of the experiment except that nearer excita tion threshold.
