Laser spectroscopy used in the investigation of the Zeeman - hyperfine structure of vanadium

Laser spectroscopy methods were used in investigations of the Zeeman - hf structure of 17 lines of atomic vanadium in the visible green - red region 568.3 - 648.1 nm. We used two methods of laser spectroscopy: the laser induced fluorescence (LIF) and fluorescence depletion spectroscopy (FDS). A hollow cathode discharge tube was the source of vanadium atoms. Zeeman structure measurements were carried out using a permanent neodymium magnet generating a field of approximately 800 G. We determined A hfs constants for 7 levels and values of the Lande gJ factors for 10 levels. We also verified the previously determined gJ factors for 12 levels and 18 hfs constants.
