摘　　要：用HFR方法对CaⅨ-KrⅩⅩⅤ离子3s2,3s3p,3s3d,3p2组态能级结构进行了理论计算.在已有实验研究的基础上,通过分析离子能级沿等电子序列的变化规律,运用最小二乘拟合方法预言计算了GeⅩⅪ-SeⅩⅩⅢ离子3s2,3s3p,3s3d,3p2组态14条精细结构能级值.在此基础上,进一步计算了GeⅩⅪ-SeⅩⅩⅢ离子3s2-3s3p,3s3p-3s3d和3s3p-3p2跃迁的23条谱线波长和相应的振子强度.计算结果与已有的实验值十分吻合,波长的最大不确定度为0.008 nm.We calculate the energy levels of configuration 3s^2 ,3s3p ,3s3d ,3p^2 for Mg-like sequence ions from CaⅨ-KrⅩⅩⅤ by using relativistic Hartree-Fock （HFR） calculations. Based on the other experimental study, we find the regularity of the energy levels for Mg-like isoelectronic sequence, and predict the energy levels of configuration 3s^2, 3s3p, 3s3d, 3p^2 for ions GeⅩⅪ - SeⅩⅩⅢ by using least-squares calculations. The wavelengths and the corresponding oscillator strengths of transitions 3s^2-3s3p ,3s3p-3s3d and 3s3p-3p^2 are calculated, too. The results obtained in this work are in good agreement with the available experimental data.
