High precision measurements of the hyperfine structure of Vanadium ions in the ultraviolet range

Abstract High resolution collinear laser spectroscopy has been performed on singly charged ions of $$^{50,51}$$ V at the IGISOL facility of the Accelerator Laboratory, University of Jyväskylä, Finland. Eleven ionic transitions were investigated in the ultraviolet wavelength range, improving the precision of the known hyperfine parameters and providing newly measured values. We report also the isotope shifts between the two natural isotopes for five of the studied transitions. These results provide benchmark data for the electronic structure of vanadium and open the way for future studies of nuclear-structure phenomena along the vanadium isotopic chain using laser spectroscopy techniques.
