摘　　要：用相对论HartreeFock方法对YⅦ—AgⅩⅤ离子4s24p3和4s24p25s组态的能级结构进行了系统的理论计算.通过分析能级结构的Slater径向积分参数沿等电子序列的变化规律,运用参数拟合外推(或内插)的方法计算了上述离子组态的能级结构参数.在此基础上,计算了Rh,Pd和AgⅩⅤ离子4s24p3(4S32,2P12,32,2D12,32)和4s24p25s(4P12,32,52,2P12,32,2D32,52,2S12)组态的精细结构能级以及这两个组态之间电偶极允许跃迁的全部35条谱线波长与相应的振子强度,其中Pd和AgⅩⅤ离子的所有数据纯属目前的预测计算值.Extensive analysis of fine-structure energy levels of configurations ,4s^24p^3（^4S2/3,^2P1/2,3/2,^D1/2,3/2） and 4s^24p^25s（^4P1/2,3/2,5/2,^2P1/2,3/2,^D2/3,5/2,^2S1/2） are made for arsenic isoelectronic sequence of ions from YⅦ to AgⅩⅤ by Hartree-Fock method with relativistic corrections （HFR） using the Cowan code. The Slater parameters of fine-structure level are obtained by least-square-fit for ions mentioned above with the available experimental data, and the unknown parameters are calculated by the generalized-least-square-fit with the extra-（inter）polation method. With these new parameter values, the fine-structure energy levels of 4s^24p^3 , 4s^24p^25s are computed. All of the 35 electronic-dipole transition wavelengths and its associated oscillator strengths between configurations 4s^24p^3 and 4s^24p^25s are calculated for RhⅩⅢ, PdⅩⅣ and Ag ⅩⅤ . The wavelength uncertainties with the available experimental values for RhⅩⅢ are mostly within 0.003 nm. All results of PdⅩⅣ and AgⅩⅤ are predicted values currently anavailable in experiment.
