摘要采用多通道R-matrix程序计算了电子与Mg5+离子碰撞激发的碰撞强度.所有的跃迁均限定在主量子数为2的态之间.计算结果与用相对论扭曲波方法得到的结果进行了比较,R-matrix方法所得的结果更好.文中列出了部分光允许跃迁的数据,可以看出,R-matrix方法更适合计算低能碰撞. The multichannel R-matrix code is employed to compute the collision strengths for electron-impact excitation of pentacid Mg ion. All the transitions are constrained in n = 2 states. The results obtained are compared with the data from relativistic distorted-wave method. A detailed comparison are tabulated for part of the optical-allowed transitions. It can be seen that the data gotten by using R-matrix are more accurate than that of distorted-wave method for low incident electron energy.
