cds-question@unistra.fratomic-physicsRadiative lifetimes, accurate to +/-5%, have been measured for 212 odd-parity levels of SmII using laser-induced fluorescence. The lifetimes are combined with branching fractions measured using Fourier transform spectrometry to determine transition probabilities for more than 900 lines of SmII. This work is the largest scale laboratory study to date of SmII transition probabilities using modern methods.2006ApJS..162..227Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/162/227CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/162/227https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/162/227http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/162/227https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/162/227https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/162/227http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/162/227GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/ApJS/162/227/table1Radiative lifetimes of Sm II from laser-induced fluorescence (LIF) measurementsJuUpper level J valuephys.atmol.qnfloatrecnoRecord number assigned by the VizieR team.
