cds-question@unistra.fratomic-physicsAbsorption or emission lines of Fe II are observed in many astrophysical spectra and accurate atomic data are required to interpret these lines. The calculation of electron-impact excitation rates for transitions among even the lowest lying levels of Fe II is a formidable task for theoreticians.2007A&A...475..765Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/475/765CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/399/799 : Fe XI trans. effective collision strengths (Aggarwal+, 2003)J/A+A/410/349 : Fe XV effective collision strengths (Aggarwal+, 2003)J/A+A/418/1171 : FeXVIII-FeXXIII effective collision strengths (Bautista+ 2004)J/A+A/429/1117 : Fe XIII effective collision strengths (Aggarwal+, 2005)J/A+A/439/1215 : Fe X trans. effective collision strengths (Aggarwal+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/475/765https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/475/765http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/475/765https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/475/765https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/475/765http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/475/765GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/475/765/table1Target state energies in rydbergs relative to the ground state of FeIIrecnoRecord number assigned by the VizieR team.
