cds-question@unistra.fratomic-physicsAbsorption or emission lines of Cr II are observed in a wide variety of astrophysical spectra and accurate atomic data are urgently needed to interpret these lines. Many of these data are impossible to measure experimentally and a full theoretical treatment is the only means by which these data can be obtained.2010A&A...524A..35Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/524/A35CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/273 : IRON Project II.
