Multi-configuration Dirac—Hartree—Fock (MCDHF) calculations for Zn-like sequence from Z = 48 to 54

Abstract

The 4s4p excitation energies and the 4s2−4s4p E1 transitions for zinc-like ions from Z = 48 to 54 are calculated by the multi-configuration Dirac—Hartree—Fock (MCDHF) method in this paper. The results for fine-structure energy levels, wavelengths and lifetimes between Z = 48 (Cd) and Z = 54 (Xe) are presented and compared with other theoretical and experimental results. The calculated values including core-valence correlation are found to be very similar to other theoretical and experimental values. We believe that our calculated values can guide experimentalists in identifying the fine-structure levels in their future work.
