Theoretical study on Electron Impact Excitation of Ni-like Au51+ ions

利用全相对论扭曲波方法和研究电子碰撞激发过程的计算程序REIE06系统计算了类镍Au51+离子从基态（3s23p63d10）n=3壳层电子3 （ = s、p、d）激发到4 、5 （ = s、p、d、f）的碰撞激发强度和截面，研究了在不同入射电子能量下截面的变化规律，通过对类镍Au51+离子涉及X射线激光跃迁的相关能级电子碰撞激发速率的计算，分析了等离子体中电子温度对碰撞过程的影响。部分计算结果与其它理论及实验结果进行了比较，取得了很好的一致性。
The Electron Impact Excitation (EIE) cross sections of Ni-like Au51+ ion from 3 （ = s、p、d） to all of 4 、5 （ = s、p、d、f）states are calculated systematically by using the fully relativistic distorted-wave (RDW) program. The rate coefficients connected with the strongest 4d-4p (J=0-1) X-ray laser transitions of Ni-like Au51+ ion are also computed systematically. The EIE cross sections versus different energies of incident electron and the rate coefficients versus different electron temperatures are studied, and some important conclusions are summarized. Also, comparisons of the present calculations with the available experimental results are made, a good agreement is found.
