Electric dipole, electric quadrupole, and magnetic dipole transition probabilities of Na-like ions, 56 ≤ Z ≤ 92

Abstract

Electric dipole, electric quadrupole, and magnetic dipole transition probabilities among states with principal quantum numbers n = 3 and 4 have been calculated using Dirac-Fock single-configuration wave functions for Na-like ions Ba 45+ through U 81+. For the theoretical energies, the Breit interaction and the Lamb-shift corrections were calculated perturbatively. Radiative lifetimes were obtained from the calculated transition probabilities.
