Abstract
Transition probabilities and lifetimes were calculated using two different local exchange approximations, the Hartree-Slater and the Optimized Hartree-Fock-Slater methods. Relativistic self-consistent-field wavefunctions were used to evaluate the radial integrals, and a comparison is made between the results obtained with the transition probability operator on the dipole velocity and dipole length forms. The agreement with available experimental lifetime data is discussed and predicted lifetimes are presented for the remaining levels. Intermediate wavefunctions were obtained with the aid of intermediate coupling coefficients evaluated from a fit to experimental energy levels.Keywords
