Fine Structure Analysis of the Configuration System of V II. Part II: Odd-Parity Levels

Abstract

The 3 d 3 4 p , 3 d 3 5 p and 3 d 2 4 s 4 p odd configurations of the V II spectrum have been reanalysed and three 3 d 2 4 s 4 p triplets are assigned higher energies than previously proposed. We have determined the fine structure parameters, the largest and next largest eigenvector percentages of levels, their calculated Landé g J -factors and predicted positions for missing experimental levels up to 100,000 cm -1 for the 3 d 2 4 s 4 p configuration. Furthermore for the first time a hyperfine structure (HFS) parametric treatment, involving levels of these two configurations has been carried out. The deduced single-electron HFS parameter values are successfully checked with those obtained by means of ab initio calculations.
