cds-question@unistra.fratomic-physicsEnergy levels, radiative rates, collision strengths, and effective collision strengths for all transitions up to and including the n=5 levels of Al XIII have been computed in the jj coupling scheme including relativistic effects. All partial waves with angular momentum J<=60 have been included, and resonances have been resolved in a fine energy grid in the threshold region. Collision strengths are tabulated at energies above thresholds in the range 170.0<=E<=300.0Ryd, and results for effective collision strengths, obtained after integrating the collision strengths over a Maxwellian distribution of electron velocities, are tabulated over a wide temperature range of 4.4<=logT_e_<=6.8K. The importance of including relativistic effects in a calculation is disc ussed in comparison with the earlier available non-relativistic results.2005A&A...432.1151Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/432/1151CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/420/783 : Electron impact excitation of Fe XVII (Aggarwal+, 2004)J/A+A/399/799 : Fe XI trans. effective collision strengths (Aggarwal+, 2003)J/A+A/407/769 : Excitation rates for transitions in Ca XV (Aggarwal+, 2003)J/A+A/410/349 : Effective collision strengths in Fe XV (Aggarwal+, 2003)J/ApJS/121/265 : Oscillator Strengths and Radiative Rates for FeXV (Deb+, 1999)J/ApJS/123/311 : Excitation rate coefficients for O III (Aggarwal+, 1999)J/A+A/418/371 : Electron impact excitation of Fe XIII (Aggarwal+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/432/1151https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/432/1151http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/432/1151https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/432/1151https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/432/1151http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/432/1151GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/432/1151/table1Comparison between NIST and our present GRASP energy levels (in Ry) for Al XIIIrecnoRecord number assigned by the VizieR team.
