摘　　要：利用考虑了电子关联效应和组态相互作用的Relativistic Hartree-Fork(HFR)和LSdependent(LS-D)的HFR自洽场方法,系统计算了Kr原子等电子系列离子的4d电子径向波函数、轨道半径、4p6→4p5 nd(4≤n≤8)辐射跃迁能和跃迁振子强度.结果显示,Kr原子的等电子系列离子4d波函数塌缩从Rb+开始,Rb+、Sr2+、Y3+离子的4d波函数塌缩是部分塌缩;对于4d波函数塌缩的离子,4p6→4p54d辐射跃迁振子强度很强,对于4d波函数发生部分塌缩的离子,4p6→4p55d、6d、7d的跃迁也有很大增强;当4d波函数完全塌缩后,辐射跃迁主要集中在4p6→4p54d跃迁.Self-consistent-field calculations of the 4 d electron radial wave function for Kr atom isoelec-tronic sequence ions have been made using relativistic Hartree-Fork （HFR） and LS-dependent HFR methods including correlation and configuration interaction .And orbital radii and the transition energies and oscillator strengths of the 4p6 →4p5 nd （4≤ n≤8） have been computed in Kr-like ions .The results show that the collapse of the 4d-wave functions start from Rb＋ in Kr-like ions .The collapse of the 4d-wave functions for Rb＋ 、Sr2＋ 、Y3＋ is partial collapse .It is found that the oscillator strengths of the 4p6→4p54d are very strong for ions in 4d-wavefunction collapse and the oscillator stregths of the 4p6 →4p5 5 d ,6 d ,7 d are also stronger for ions in 4 d-wavefunctions partial collapse .And it is found that the bulk of transition oscillator strengths is concentrated at the 4p6 →4p54d after 4d-wave function is completely collapsed .
