Relativistic excitation energies and oscillator strengths for the (5s2)1S0→(5s5p)1P1,3P1 transitions in Cd-like ions

Abstract
Excitation energies and oscillator strengths from the 1 S0 ground state to the first 3 P1 and 1 P1 excited states of Cd-like ions are calculated by using the multiconfiguration relativistic random-phase approximation. Results are compared with other theories and with experiment. The discrepancy between the theoretical and experimental results is discussed.
