Show affiliations


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 ns2 1S0nsnp 1P1, 3P1 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.
