摘　　要：用多组态HFR方法对CuⅩⅧ离子n=3complex组态能级结构进行了综合的分析与计算.在已有实验工作的基础上,运用参数拟合方法获得了能级结构参数的最佳计算值,由这些参数值预测计算了CuⅩⅧ离子n=3complex组态能级以及3s2—3s3p,3s3p—3p2,3p2—3p3d,3s3d—3p3d,3p3d—3d2组态能级跃迁的谱线波长,振子强度和跃迁概率.The energy levels of magnesium_like ion Cu ⅩⅧ in n=3complex configurations are computed by multi_configuration Hartree_Fock with relativistic corrections (HFR) method.The Slater parameters are optimized with the least_square_fit(LSF) technique based on the available experimental data.With these new parameters, the wavelengths,oscillator strengths and transition probabilities for transitions 3s2—3s3p,3s3p—3p2,3p2—3p3d,3s3d—3p3d,3p3d—3d2 in n=3complex configurations for magnesium_like Cu ⅩⅧ are predicted.
