cds-question@unistra.fratomic-physicsIn this paper we report calculations for energy levels and radiative rates for transitions in Fe IX. The General purpose Relativistic Atomic Structure Package (GRASP) has been adopted for the calculation of energy levels and radiative rates. Energies for the lowest 360 levels, including those from the (1s^2^2s^2^2p^6^) 3s^2^3p^6^, 3s^2^3p^5^3d, 3s3p^6^3d, 3s^2^3p^4^3d^2^, and 3s^2^3p^5^4l configurations of Fe IX, are reported. Additionally, radiative rates, oscillator strengths, and line strengths are reported for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transitions among these levels. Comparisons are made with the available results in the literature, and the accuracy of the present data is assessed.2006A&A...460..331Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/460/331CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/427/763 : Fe X E1, E2,M1 and M2 transitions (Aggarwal+, 2004)J/A+A/439/1215 : Fe X effective collision strengths (Aggarwal+, 2005)J/A+A/399/799 : Fe XI effective collision strengths (Aggarwal+, 2003)J/A+A/418/371 : Fe XIII electron impact excitation (Aggarwal+, 2004)J/A+A/429/1117 : Fe XIII effective collision strengths (Aggarwal+, 2005)J/ApJS/121/265 : Fe XV oscillator Strengths and Radiative Rates (Deb+, 1999)J/A+A/410/349 : Fe XV effective collision strengths (Aggarwal+, 2003)J/A+A/450/1249 : Fe XVI radiative and excitation rates (Aggarwal+, 2006)J/A+A/420/783 : Fe XVII electron impact excitation (Aggarwal+, 2004)J/A+A/416/383 : Fe XVIII transition probabilities (Jonauskas+, 2004)J/ApJS/123/311 : O III excitation rate coefficients (Aggarwal+, 1999)J/A+A/407/769 : Ca XV excitation rates for transitions (Aggarwal+, 2003)J/A+A/432/1151 : Al XIII electron impact excitation (Aggarwal+, 2005)J/A+A/436/1141 : Ar XIII, Ar XIV + Ar XV radiative rates (Aggarwal+, 2005)J/A+A/441/831 : Ar XVII electron impact excitation (Aggarwal+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/460/331https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/460/331http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/460/331https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/460/331https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/460/331http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/460/331GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/460/331/table1Energy levels and lifetimes ({tau}) of Fe IXtau?
