cds-question@unistra.fratomic-physicsWe tabulate theoretical line strengths, f-values and transition energies for the beryllium-like ion Fe XXIII. Transitions are between levels 2l_1_2l_2_S'L'J' and 2l_3_nl_4_SLJ with n = 2, 3, 4. The calculation uses the well known configuration interaction program CIV3 in which relativistic effects are allowed for by means of the Breit-Pauli approximation. We give a detailed comparison of our oscillator strengths with those which Chen & Ong (1998, Phys. Rev. A, 58, 1070) obtained using the relativistic Dirac code GRASP2.2001A&A...365..266Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/365/266CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/103/273 : IRON Project II IR collision strengths of C-like ionsJ/A+A/283/319 : IRON Project III B-like ionsJ/A+AS/108/1 : IRON Project V Collision strengths of O-like ionsJ/A+A/293/953 : IRON Project VI Fe II collision strengthsJ/A+A/293/967 : IRON Project VII Fe II radiative transitionsJ/A+AS/109/193 : IRON Project VIII Electron excitation of Ti-like ionsJ/A+AS/119/509 : IRON Project XVII Radiative transition in Fe IIIJ/A+AS/119/523 : IRON Project XVIII Electron impact for Fe IIIJ/A+AS/120/361 : IRON Project XIX Fe II radiative transitionsJ/A+AS/123/159 : IRON Project XXII C and O radiative ratesJ/A+AS/123/575 : IRON Project XXIII Fe XXII excitation rate coefficientsJ/A+AS/126/373 : IRON Project XXVII Fe IV collision strengthsJ/A+AS/131/499 : IRON Project XXIX Boron isoelectronic sequenceJ/A+AS/131/153 : IRON Project XXXI Fe XII electron excitationJ/A+AS/135/347 : IRON Project XXXV Fe XXIV & Fe XXV oscillator strengthsJ/A+AS/136/395 : IRON Project XXXVII Fe VI collision strengthsJ/A+AS/137/165 : IRON Project XXXVIII Fe XV fine-structure transitionsJ/A+AS/143/483 : IRON Project XLII Fe XXI electron impact excitationJ/A+AS/144/141 : IRON Project XLIII Fe V transition probabilitiesJ/A+AS/147/111 : IRON Project XLIV Fe VI trans. prob. & line ratioJ/A+AS/147/253 : IRON Project XLV Ar XIII, Fe XXI trans. probabilitiesJ/A+A/365/268 : IRON Project XLVII Ni III electron impact excitationJ/A+A/389/716 : Oscillator strengths for Li-like ions (Nahar, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/365/266https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/365/266http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/365/266https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/365/266https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/365/266http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/365/266GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/365/266/table1Fe XXIII radial orbital parametersrecnoRecord number assigned by the VizieR team.
