Relativistic configuration-interaction oscillator strengths for lowestE1transitions in silver and gold isoelectronic sequences

Relativistic oscillator strengths are computed for $n{s}_{1/2}\text{−}n{p}_{1/2,3/2}$ 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.
