Abstract

Four new fine structure energy levels of atomic vanadium have been discovered for the first time. Experiments were carried out with laser-induced fluorescence spectroscopy and optogalvanic spectroscopy using tunable continuous wave lasers in the wavelength ranges between 750 nm and 850 nm and between 590 nm and 650 nm, respectively. The new levels, all lying in the 42 400 to 49 940 cm-1 energy range, were each experimentally confirmed by two or more observed transitions involving previously known energy levels. Accurate energy level values were found using lines measured by Fourier transform spectroscopy. The values for the total angular momentum quantum numbers J of the new levels were found by the analysis of the hyperfine structure of the spectral lines investigated. Magnetic dipole hyperfine structure constants A for all new levels were determined. Additionally, for one previously known energy level the magnetic dipole hyperfine structure constant A from the literature was corrected.
