THE SPECTRUM AND TERM ANALYSIS OF V I

High-resolution spectra of neutral vanadium have been recorded by Fourier transform spectrometry in the region 1492-28600 angstrom (67020-3496 cm(-1)) with vanadium-neon and vanadium-argon hollow cathode lamps as sources. Most of the lines exhibit fully or partly resolved hyperfine structure, but the wavenumber uncertainty for the center of gravity of the strongest lines is 0.002 cm(-1). Of the previously published energy levels of VI, 72 have been revised and 37 discarded. In addition, 89 new levels have been found. In total 346 odd levels and 198 even levels are presented. Wavenumbers and classifications are given for 3130 VI lines.
