cds-question@unistra.fratomic-physicsCross sections for the excitation of transitions in the tantalum atom (Z=73) not related to the ground state have been measured using extended crossed beams and optical spectroscopy. The total excitation cross sections for 23 energy levels of TaI have been determined.2002AZh....79..932Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/79/932CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/79/932https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/79/932http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/79/932https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/79/932https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/79/932http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/79/932GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/AZh/79/932/table1Excitation cross sections for spectral lines of the tantalum atomJInner quantum numberphys.atmol.qncharTransType of transitionmeta.id;phys.atmol.transitionrecnoRecord number assigned by the VizieR team.
