Energies of 5lj(l=s,p,d,f,g) and 4fj states in neutral Ag and Ag-like ions with nuclear charges Z=48–100 are calculated using relativistic many-body perturbation theory. Reduced matrix elements, oscillator strengths, transition rates, and lifetimes are calculated for the 17 possible 5lj-5lj′′ and 4fj-5lj′ electric-dipole transitions. Third-order corrections to energies and dipole matrix elements are included for neutral Ag and for ions with Z<~60. Second-order corrections are included for Z>60. Comparisons are made with available experimental data for transition energies and lifetimes. Correlation energies and transition rates are shown graphically as functions of nuclear charge Z for selected cases. These calculations provide a theoretical benchmark for comparison with experiment and theory.
