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 probabili ties is investigated. An alternative approach to the generation of spin orb itals used to construct configuration interaction wave functions is propose d. This is a configuration interaction method with relativistic wave functi ons generated using an nb initio model potential [CIDF(MP)]. The CIDF(MP) m ethod is tested for resonance spin-forbidden and spin-allowed 6s(2 1)S(0)-6 s6p transitions in mercury and later successfully used for 6s6p-6s7s transi tion array.
