摘要: 对类锌等电子序列ZnI–SnXXI离子n=4Complex组态的能级结构和组态相互作用进行了理论分析。通过分析HXR方法理论计算值与实验值之差DE随Zc的变化关系，找出了用于最小二乘拟合计算的半经验拟合公式，用此公式预测了CdXIX–InXX离子n=4Complex中至今还没有实验值的部分能级。给出了4s2-4s4p, 4s4p-4s4d跃迁波长和相应的HXR方法计算的振子强度，同时也对预测能级值的可靠性作了说明。Abstract: In this paper, the theoretical atomic energy level values for configurations 4s2, 4s4p, 4s4d, 4s5s of zinc –like isoelectronic sequence ions from Rh X VI to In XX are calculated with HXR method in Cowan’s computer code. By analysing variation of the differences D E between theoretical and experimental energy level values with Zc (Zc=Z–N+1)along the isoelectronic sequences, we put forward a new fit formula. Using this formula and the FORTRAN programe designed by us, we have made a systematic fit calculation for the energy level values of configuration mentioned above. Some unknown energy levels belonging to the ions (RhXVI –In XX)are predicted by interpolate and extrapolate. Also, the 4s2 –4s4p, 4s4p –4s4d transition wavelengths and the corresponding HXR calculating oscillator strengt
