Atomic transition probabilities from the relativistic pseudopotential approach

The 'relativistic pseudopotential approach' is applied to the calculation of electric-dipole transition probabilities in the valence shell of heavy atoms. An adequate transition operator is derived. The lowest spin-allowed and spin-forbidden transitions of the heavier group I and II elements and a series of higher transitions of Ca I and II, Cs, I, Ba I and II, Au I and Hg I are calculated. The influence of the core-valence correlation is investigated with Hameed's core-polarisation correction.
