cds-question@unistra.fratomic-physicsspectroscopyThe spectrum and extended term analysis of V II are presented. Fourier transform spectrometry was used to record high resolution spectra of singly ionized vanadium in the region 1492-5800 {AA} (67020-17260/cm) with vanadium-neon and vanadium-argon hollow cathode lamps as sources. The wavenumber uncertainty for the center of gravity of the strongest lines is typically 0.002/cm, an improvement of an order of magnitude over previous measurements. Most of the lines exhibit partly resolved hyperfine structure. The V II energy levels in the 1985 compilation of Sugar and Corliss have been confirmed and revised, with the exception of the high-lying 4f levels and eight of the lower levels. Thirty-nine of the additional eighty-five high levels published by Iglesias et al. (1988, Publicaciones del Instituto Optica Daza de Valdes Madrid, 47, 1) have also been confirmed and revised, and three of their missing levels have been found. The energy uncertainty of the revised levels has been reduced by about an order of magnitude. In total, 176 even levels and 233 odd levels are presented.2013ApJS..207...13Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/207/13CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/207/20 : Parity-forbidden [Co II] and [V II] lines (Ruffoni+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/207/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/207/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/207/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/207/13https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/207/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/207/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJS/207/13/table1V.II (23.01) linelist of observed transitionsrecnoRecord number assigned by the VizieR team.
