Relativistic configuration-interaction study of transition probabilities in mercury with ab initio model potential wave functions -: art. no. 064501

The relativistic configuration-interaction method based on numerical Dirac-Fock wave functions (CIDF) is employed to determine 6s6p P-3(0,1,2), P-1(1)-6s7s S-3(1), S-1(0) transition energies and probabilities in mercury. The influence of electron correlation on both transition energies and probabilities is investigated. An alternative approach to the generation of spin orbitals used to construct configuration interaction wave functions is proposed. This is a configuration interaction method with relativistic wave functions generated using an nb initio model potential [CIDF(MP)]. The CIDF(MP) method is tested for resonance spin-forbidden and spin-allowed 6s(2 1)S(0)-6s6p transitions in mercury and later successfully used for 6s6p-6s7s transition array.
