| 摘 要： | 用多组态HXR理论方法对KrⅣ-CdⅩⅥ离子4s^24p^3和4s4p^4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4s^24p^3和4s4p^4组态能级的实验观测值与HXR计算结果之差AE沿等电子序列变化规律的分析．找出了△E随有效核电荷数Zc变化的规律，预言并计算了PdⅩⅣ-CdⅩⅥ离子4s^24p^3和4s4p^4组态能级，大部分预言计算值与实验结果的偏差小于100cm^-2。由此还进一步计算了PdⅩⅣ-CdⅩⅥ离子4s^24p^3—4s4p^4跃迁的谱线波长、振子强度和跃迁概率。结果表明：除了4s^24p^3D5/2-4s4p^4^2D5/2跃迁的谱线波长(29．992nm)与实验值相差0．018nm外．对于其余5条谱线．预言值与实验值的偏差均不超过0．005nm。

| Abstract: | In this paper, fine-structure energy levels of configurations 4s~24p~3 and 4s4p~4 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 Z_c 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 uncentainty of most predicted energy level values with the associated experimental results are not more than 100 cm-1. The wavelengths, oscillator strengths and probabilities of transitions 4s~24p~3—4s4p~4 calculated with HXR method are given here too. The predicted wavelengths of transition 4s~24p~3—4s4p~4 for PdⅩⅣ are in well agreement with the experimental ones within 0.005 nm except that of transition 4s~24p~3 ~2D_(5/2)—4s4p~4 ~2D_(5/2) which is 0.018nm,and the other results of trasitions 4s24p3-4s4p for ions from PdXIV to Cd X VI are sheer predicted ones. |
