cds-question@unistra.fratomic-physicsCollision strengths for transitions among the lowest 48 fine-structure levels belonging to the (1s^2^2s^2^2p^6^) 3s^2^3p^4^, 3s3p^5^, 3s^2^3p^3^3d and 3p^6^ configurations of Fe XI have been calculated using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2003, Comput. Phys. Commun., in prep.). Results are tabulated at energies above thresholds in the range 10<=E<=100Ry, although resonances have been resolved in a fine energy mesh in the thresholds region. Effective collision strengths, obtained after integrating the collision strengths over a Maxwellian distribution of electron velocities, are also tabulated over a wide electron temperature range below 5x10^6^K. Comparisons with other available results are made, and the accuracy of the present data is assessed.2003A&A...399..799Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/399/799CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/273 : C-like ions Effective collision strengths (Lennon+ 1994)J/A+AS/108/1 : O-like ions Effective collision strengths (Butler+, 1994)J/A+AS/125/543 : Mg VI Effective collision strengths (Ramsbottom+ 1997)J/ApJS/123/295 : Electron impact excitation in Fe XI (Gupta+, 1999)J/A+A/410/349 : Fe XV Effective collision strengths (Aggarwal+, 2003)J/A+A/427/763 : Radiative rates of Fe X (Aggarwal+ 2004)J/A+A/418/363 : Cl II Effective collision strengths (Tayal+, 2004)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/430/725 : N II effective collision strengths (Hudson+, 2005)J/A+A/432/731 : C II Effective collision strengths (Wilson+, 2005)J/A+A/436/1131 : Al III effective collision strengths (Hudson+ 2005)J/A+A/460/331 : Fe IX radiative and excitation rates (Aggarwal+, 2006)J/A+A/463/399 : Fe XVI radiative rates (Aggarwal+, 2007)J/A+A/484/879 : Fe XXVII 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/399/799https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/399/799http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/399/799https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/399/799https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/399/799http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/399/799GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/399/799/table1State definitions and energy levels (in Ry) for S-like Fe XIrecnoRecord number assigned by the VizieR team.
