We have measured the hyperfine structure of 51V II using the technique of collinear fast-ion-beam laser spectroscopy. The output of a dye laser was applied collinearly to an accelerated 50 ke V ion beam to produce laser induced fluorescence spectra for the metastable 3d34s and 3d4 configurations. The technique of laserradio- frequency double resonance, which utilizes an optical photon to deplete a hyperfine state and an rf photon to repopulate the state, was used to measure the hyperfine intervals to a high precision. These measurements of the hyperfine intervals allowed the determination of the magnetic dipole and electric quadrupole constants for comparison with ab initio theoretical calculations.
