“…The interpretation has been carried out, as for instance in [11][12][13], based on a model space for even-parity and refined multiconfiguration fine structure calculation including some strongly interacting configurations for odd-parity. We also computed through ab initio procedure V II lifetime values, having this time recourse to Cowan code.…”

“…Using a linkedparameter technique of level-fitting calculations [9][10][11][12][13] in a multiconfiguration basis a parameteric analysis of fine structure for even-parity levels of V II, involving six configurations, has been performed and the single-electron hfs parameters are determined in their entirety for 51 V II for the model space (3dþ4s) 4 with good confidence, as is seen by the standard deviation value obtained for fitted parameters: 1.3 mK. Furthermore the 3d 3 4p, 3d 3 5p and 3d 2 4s4p odd configurations for the same ion spectrum have been reanalysed and for the first time an hfs parametric treatment, involving levels of these 3 configurations, has been carried out.…”

“…A many-body parametrisation calculation for the HFS analysis allows us to exploit the similarities between configuration interaction effects seen in spin-orbit and hyperfine splitting. Using Equations (4) and (5) in [19] for the A and B HFS constants, the radial parameters k nl a κ , k nl b κ , a i and b i are determined by fits to experimental values.…”

The 3d 3 4p, 3d 3 5p and 3d 2 4s4p odd configurations of the V II spectrum have been reanalysed and three 3d 2 4s4p 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 gJ-factors and predicted positions for missing experimental levels up to 100,000 cm −1 for the 3d 2 4s4p 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.

Using a linked-parameter technique of level-fitting calculations in a multi configuration basis, a parametric analysis of fine structure (fs) for even-parity levels of V II, involving six configurations, has been performed. This led us to exchange the assignments of two triplets, 3d 3 ( 2 F)4s c 3 F and 3d 4 d 3 F, reported in earlier analyses as being located at 30,300 cm −1 and 30,600 cm −1 , respectively. This is confirmed by experimental hyperfine structure (hfs) A constants, used as fingerprints. Moreover, the current singlet 3d 2 4s 2 1 D2 position is likely too high. The fs parameters, magnetic Landé g-factors, and the percentage of leading eigenvectors of levels are calculated. We present also predicted singlet, triplet and quintet positions for missing experimental levels up to 100,000 cm −1 . The single-electron hfs parameters are determined in their entirety for 51 V II for the model space (3d + 4s) 4 with good accuracy. For the model space (3d + 4s) 4 of 51 V II the single-electron hfs parameters are computed; furthermore, our achieved theoretical evaluations of the single-electron hfs parameters, thanks to the use of ab initio calculations, reinforce the validity of these hfs parameter values, deduced from experimental data.
