New even parity fine structure energy levels of atomic vanadium

Abstract

<p>Four new fine structure energy levels of atomic vanadium have been discovered for the first time. Experiments<br> were carried out with laser-induced fluorescence spectroscopy and optogalvanic spectroscopy using tunable<br> continuous wave lasers in the wavelength ranges between 750 nm and 850 nm and between 590 nm and 650 nm,<br> respectively. The new levels, all lying in the 42 00 to 49940 cm^-1&nbsp;energy range, were each experimentally<br> confirmed by two or more observed transitions involving previously known energy levels. Accurate energy level<br> values were found using lines measured by Fourier transform spectroscopy. The values for the total angular<br> momentum quantum numbers J of the new levels were found by the analysis of the hyperfine structure of the<br> spectral lines investigated. Magnetic dipole hyperfine structure constants A for all new levels were determined.<br> Additionally, for one previously known energy level the magnetic dipole hyperfine structure constant A from the<br> literature was corrected.</p>
