Theoretical Calculations on Oscillator Strengths of 1s^2nd-1s^2n'f(n≤9)Dipole Transitions for Ni^(25+) Ion

利用多组态相互作用方法构造了高离化Ni25+离子1s2nl(n≤9,l=d,f)Rydberg序列的波函数,计算了1s2nd-1s2n'f(3≤n≤9;4≤n'≤9)偶极跃迁在长度、速度和加速度三种规范下的振子强度,得到的计算结果彼此符合的较好.本文还将振子强度与量子亏损理论相结合,计算了从任一给定初态到末态所有分立态和连续态的振子强度和振子强度密度,实现了全能域光谱特性的理论预言.

The wave function of1s2nl （n≤9,l=d,f） states for highly charged Ni25＋ ion is constructed with multi-configuration interaction method. The oscillator strengths in length, velocity and acceleration expressions for 1s2 nd-1s2n＇f （n,n＇ ≤9） dipole transitions are calculated, the agreement among them is satisfying. Combining theoscillator strength with the single channel quantum defect theory, the discreet oscillator strengths and oscillatorstrength density corresponding to the bounding-free transition from a certain initial state to all the final states are obtained.
