Energy levels of ionized vanadium (V II)

The experimentally derived energy levels belong to the configurations 3d^4^, 3d^3^ns (n=4,5,6), 3d^3^np, and 3d^3^nd (n=4,5), 3d^3^4f, 3d^2^4s^2^, and 3d^2^4s4p. Also included are values for some forbidden lines that may be of interest to the astrophysical community.

Experimental Lande g-factors and leading percentages for the levels are included when available, as well as Ritz wavelengths calculated from the energy levels. Wavelengths and transition probabilities are reported for 3568 and 1896 transitions, respectively. From the list of observed wavelengths, 407 energy levels are determined.
