CRITICALLY EVALUATED ENERGY LEVELS, SPECTRAL LINES, TRANSITION PROBABILITIES, AND INTENSITIES OF SINGLY-IONIZED VANADIUM (V II)
Alexander Kramida, Edward B. Saloman
The energy levels, observed spectral lines, and transition probabilities of singly-ionized vanadium, V II, have been compiled. Also included are values for some forbidden lines which may be of interest to the astrophysical community. Experimental Landé 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. The observed intensities are provided normalized to a common scale. From the newly optimized energy levels, a revised value for the ionization energy is derived, 117930(60) cm−1, corresponding to 14.621(7) eV. This agrees with the previously recommended value, but has a twice larger uncertainty.
