中文摘要：
利用相对论扭曲波方法和新发展的研究电子碰撞激发过程的计算程序REIE06,系统计算了电子碰撞激发高离化态类镍Gd36＋和Rn58＋—U64＋（Z=86—92）离子从基态到4l（l=s,p,d,f）次壳层精细结构能级的碰撞强度和截面.研究了随等电子系列变化时,从基态到与X射线激光有关的3d94p和3d94d激发态能级的电子碰撞激发截面随Z的变化,讨论了强的组态相互作用对高离化态类镍离子截面的影响.通过对Gd36＋离子涉及X射线激光跃迁的相关能级电子碰撞激发速率系数的计算,分析了等离子体中电子温度对碰撞过程的影响.同时,目前部分计算结果与以往的理论结果进行了比较,得到了很好的一致性.
英文摘要：
A fully relativistic distorted-wave method and the corresponding procedure REIE06 have been developed recently to study the electron impact excitation processes of highly charged ions. In this study, we calculated the collision strengths, cross sections and rate coefficients for electron impact excitation of highly charged Nickel-like Gd^36＋ , Rn^58＋ --U^64＋ （ Z = 86-92）ions from the ground state to 106 low-lying excitated states. In the calculations, the relativistic effects, electron correlation effects, Breit interactions and high partial wave contributions are considered systematically. Based on the calculations, we studied the contribution of Breit interaction to collision strengths, the cross sections connected with the strongest 4d-4p （ J = 0-1 ） X-ray laser transitions along the Ni-like sequence, and the effects of strong configuration interaction on cross sections from the ground state 3d^101S0 to the （3d3/24d5/2）1, （3d3/24d3/2）t and （3p3/24p1/2）1 states. A comparison was made between the present results and previous theoretical calculations for collision strengths of Gd^36＋ and U^64＋ ions, and rate coefficients of Gd^36＋ ion, good agreement was obtained.
