Extended analysis of the Eu III spectrum.

Abstract (from CDS):

We create an EuIII new atomic data set for interpreting the spectra of chemically peculiar stars by an extended analysis of the doubly-ionized europium. We classified EuIII spectral lines from a laboratory wavelength list with the support of energy and transition probability predictions in the Racah-Slater approach, using the Cowan codes and generalized least-squares fit (GLS) studies along the sequence of doubly-ionized lanthanides. More than thirty new levels and ninety classified lines are established in EuIII. Improved prediction of the EuIII spectrum was achieved by using scaling factors for ab initio energy integrals, as well as effective configuration interaction parameters supplied by GLS studies. Transition probabilities, oscillator strengths, and Lande g-factors are calculated for the lines in the region 2000-9995Å.
