Relativistic configuration-interaction oscillator strengths calculations with ab initio screened model-potential wavefunctions

The relativistic configuration-interaction (CI) method with numerical Dirac-Fock wavefunctions generated in the field of ab initio screened model potential is used to compute oscillator strengths for some spin-allowed and spin-forbidden ns(2) S-1(0-nsnp) P-1(1), 3P(1) transitions in light systems with two valence electrons: beryllium, magnesium and zinc. The present results are discussed and compared with other theoretical and experimental data available.
