cds-question@unistra.fratomic-physicsEnergies for the lowest 49 levels among the 1s^2 and 1snl (n=2-5) configurations of Ar XVII have been calculated using the GRASP code of Dyall et al. (1989, Comput. Phys. Commun., 55, 424). Additionally, radiative rates, oscillator strengths, and line strengths are calculated for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transitions among these levels. Furthermore, collision strengths have also been calculated for all the 1176 transitions among the above 49 levels using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2005, Comput. Phys. Commun., in prep.), over a wide energy range up to 580Ryd. Resonances have been resolved in the threshold region, and effective collision strengths have been obtained over a wide temperature range up to log T_e_=7.2K. Comparisons are made with the limited results available in the literature, and the accuracy of the data is assessed. Our energy levels are estimated to be accurate to better than 0.1%, whereas results for other parameters are probably accurate to better than 20%.2005A&A...441..831Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/441/831CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/436/1141 : Radiative rates in Ar XIII, Ar XIV + Ar XV (Aggarwal+, 2005)J/A+A/487/383 : Ar XVIII radiative and excitation rates (Aggarwal+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/441/831https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/441/831http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/441/831https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/441/831https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/441/831http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/441/831GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/441/831/table2Transition energies, radiative rates, oscillator strengths and line strengths for electric dipole (E1) and quadrupole (E2) transitions in Ar XVIIii levelmeta.idintjj levelmeta.idintrecnoRecord number assigned by the VizieR team.
