摘要
用HFR方法对类镉等电子序列IⅥ-SmⅩⅤ离子5s2,5p2,5s5d,5s5p组态能级结构进行系统的理论计算。在已有实验研究的基础上,通过分析各能级值的HFR理论计算值与相应实验值之差随着Zc沿等电子序列的变化规律,找出用于最小二乘拟合(LSF)计算的半经验拟合公式,结合设计的FORTRAN程序,预言出Nd-SmⅩⅤ离子n=5complex中至今还没有实验值的部分能级,能级的计算结果与已有实验值吻合得很好,同时给出了5s2—5s5p,5s5p—5p2,5s5p—5s5d跃迁谱线波长和跃迁概率。
The energy levels of the n=5 complex configuration 5s2,5s5p,5s5d and 5p2 were computed for Cd Ⅰ isoelectronic sequence ions from I Ⅵ to Sm ⅩⅤ by Hartree-Fock with relativistic corrections（HFR） method.By analyzing the variation of difference ΔE between energy levels calculated by HFR method and the experimental values with Zc along this isoelectronic sequence,the authors put forward a new fitting formula for generalized-least-square-fit（LSF） calculation.Using this formula and the FORTRAN programme designed by us,the energy levels of configurations mentioned above were calculated.The unknown energy levels of configuration 5s2,5s5p,5s5d and 5p2 for ions from Nd -Sm ⅩⅤ were predicted by extrapolation（or interpolation）.Also,the wavelengths and HFR probabilities of transition 5s2—5s5p,5s5p—5p2 and 5s5p—5s5d were computed.The calculated energy levels and wavelength results are in good agreement with corresponding experimental data reported in the references.
