Abstract Extensive analysis of fine-structure energy levels of configurations 4s24p3(4S3/2,2P1/2,3/2, 2D1/2,3/2)and 4s24p25s(4P1/2，3/2，5/2,2P1/2,3/2, 2D3/2,5/2，2S1/2) 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 4s24p3, 4s24p25s are computed. All of the 35 electronic-dipole transition wavelengths and its associated oscillator strengths between configurations 4s24p3 and 4s24p25s are calculated for Rh，Pd and AgⅩⅤ. The wavelength uncertainties with the available experimental values for Rh are mostly within 0.003nm. All results of Pd and AgⅩⅤ are predicted values currently anavailable in experiment.
