Transition probabilities for 5s–5p, 5p–5d, 4f–5d, and 5d–5f transitions in Ag-like ions with Z = 50–86

The wavelengths, electric dipole transition probabilities, and oscillator strengths are calculated for transitions between low-lying states (5s–5p, 5p–5d, 4f–5d, and 5d–5f) in the silver isoelectronic sequence (50 ⩽ Z ⩽ 86) using relativistic perturbation theory with a zero-approximation model potential. The results are compared with the corresponding data of the relativistic Hartree–Fock theory and the relativistic many-body perturbation theory. The results of these three theoretical approaches are compared with available experimental data for the level lifetimes. Possible reasons for some disagreements are discussed.
