CORE-POLARIZATION EFFECTS FOR THE (6S2) S-1(0) -] (6S6P) P-3(1)O P-1(1)O TRANSITIONS IN HG-LIKE IONS

Excitation energies and oscillator strengths from the S-1(0) ground st ate to the first P-3(1)o, and P-1(1)o excited states of Hg-like ions a re calculated by using the multiconfiguration relativistic random-phas e approximation including excitation channels from core electrons. The discrepancies between the theoretical and experimental results are mu ch reduced for the oscillator strengths but more enhanced for the exci tation energies when these core-polarization effects are taken into ac count.
