Relativistic configuration-interaction oscillator strengths for lowest E1 transitions in silver and gold isoelectronic sequences

Relativistic oscillator strengths are computed for ns(1/2)-np(1/2,3/2) transitions in silver and gold isoelectronic sequences employing configuration-interaction method with numerical Dirac-Fock wave functions generated with noninteger outermost core shell occupation number. This method is optimized to represent efficiently the core-valence electron correlation that is known to be important for transitions under consideration. The presented results are compared with our earlier data computed with core-valence correlation represented in the semiclassical core polarization picture within single configuration Dirac-Fock scheme as well as available experimental values.
