Core-polarization effects in doubly ionized cerium (Ce III) for transitions of astrophysical interest.

BIEMONT E., QUINET P. and RYABCHIKOVA T.A.

Abstract (from CDS):

The importance of core-polarization effects on oscillator strength determination in Ce iii is emphasized. The inclusion of these effects in relativistic Hartree-Fock (HFR) calculations leads to theoretical lifetime values for some 4f6p levels of this ion in close agreement with recent time-resolved laser-induced fluorescence measurements. These new atomic data, the most accurate to date, have allowed the refinement of the stellar abundance determination of cerium in the chemically peculiar star HD 192913, but have not altered in a drastic way the conclusions derived in recent analyses regarding the overabundance of this element.
