Theoretical Calculating Wavelengthes and Oscillator Strengthes for Zn Like RhⅩⅥ InⅩⅩ with n=4 Complex

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ΔＥ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４ｓ２－４ｓ４ｐ，４ｓ４ｐ－４ｓ４ｄ跃迁波长和相应的ＨＸＲ方法计算的振子强度。

In this paper,the theoretical atomic energy level values for configurations 4s 2,4s4p,4s4d,4s5s of zinc-like isoelectronic sequence ions from Rh ⅩⅥ to In ⅩⅩ are calculated with HXR method in Cowan′s computer code. By analysing variation of the differences ΔE between theoretical and experimental energy level values with Z c(Z c=Z-N+1) along the isoelectronic sequences,we put forward a new fit formula. Using this formula and the FORTRAN programe disigned 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 (Rh ⅩⅥ -In ⅩⅩ )are predicted by interpolate and extrapolate. Also,the 4s 2-4s4p,4s4p,4s4p-4s4d transition wavelengths and the corresponding HXR calculating oscillator strengths are givn here too.
