Radiative lifetime, oscillator strength and Landé factor calculations in doubly ionized europium (Eu III)

Abstract

A set of transition probabilities has been calculated for Eu III transitions of astrophysical interest particularly for the study of chemically peculiar stars. They were obtained taking configuration interaction and core-polarization effects into account. The accuracy of the new scale of oscillator strengths, which differs substantially from previous results, has been assessed through comparisons with recent time-resolved laser-induced fluorescence measurements of radiative lifetimes.
