摘要: 用多组态HXR理论方法对KrIV-CdXVI离子4s24p3和4s4p4组态的精细结构能级进行了分析计算。在已有研究工作的基础上，通过对4s24p3和4s4p4组态能级的实验观测值与HXR计算结果之差ΔE沿等电子序列变化规律的分析，找出了ΔE随有效核电荷数Zc变化的规律，预言并计算了PdXIV-CdXVI离子4s24p3和4s4p4组态能级，大部分预言计算值与实验结果的偏差小于100 cm-1。由此还进一步计算了PdXIV-CdXVI子4s24p3－4s4p4跃迁的谱线波长、振子强度和跃迁概率。结果表明：除了4s24p3 2D5/2－4s4p4 2D5/2跃迁的谱线波长（29.992 nm）与实验值相差0.018 nm外，对于其余5条谱线，预言值与实验值的偏差均不超过0.005 nm。Abstract: In this paper, fine-structure energy levels of configurations 4s24p3 and 4s4p4 for Arsenic isoelectronic sequence ions from KrIVto CdXVI are analysed by multi-configuration Hartree-Fock plus exchange-statistical-potential with relativistic corrections (HXR) method in Cowan'code. By analyzing variation of differences between the experimental data and the associated theoretical energies with Zc along the sequence, a new formula has been found for fit calculation. With this new formula, the fine-structure levels of the configurations mentioned above are predicted, the uncertainty of most predicted energy level values with the associated experimental results are not more than 100 cm-1.
