Extended analysis of fine-structure energy levels of 4s24p3 and 4s4p4 for ions from PdXIV to Cd XVI

In this paper, fine-structure energy levels of configurations 4s24p3 and 4s4p4 for Arsenic isoelectronic sequence ions from KrIVto CdXVI are analysed by multi-configuration Hartree-Fock plus exchange-statistical-potential with relativistic corrections　(HXR) method in Cowan'code. By analyzing variation of differences between the experimental data and the associated theoretical energies with Zc along the sequence, a new formula has been found for fit calculation. With this new formula, the fine-structure levels of the configurations mentioned above are predicted, the uncertainty of most predicted energy level values with the associated experimental results are not more than 100 cm-1. The wavelengths, oscillator strengths and probabilities of transitions 4s24p3_4s4p4 calculated with HXR meth
