Abstract
Energy levels, wavelengths, transition probabilities, oscillator strengths, and line strengths have been calculated for allowed electric dipole 4s (2) 4p-4s4p (2) and 4s (2) 4p-4s (2) 4d transitions of Gallium-like ions from Z = 54 to 59, Xe XXIV, Cs XXV, Ba XXVI, La XXVII, Ce XXVIII, and Pr XXIX. The fully relativistic multiconfiguration Dirac-Fock method, taking into account both correlations within the n = 4 complex and the quantum electrodynamic effects, has been used in the calculations. The results have been compared with the available experimental and other theoretical results.
