cds-question@unistra.fratomic-physicsIn this paper we report calculations for energy levels, radiative rates, and excitation rates for transitions in O IV. The GRASP (general-purpose relativistic atomic structure package) and FAC (flexible atomic code) we adopted for calculating energy levels and radiative rates, and the Dirac atomic R-matrix code (DARC) used to determine the excitation rates. Oscillator strengths and radiative rates are reported for all E1, E2, M1, and M2 transitions among the lowest 75 levels of O IV. Additionally, lifetimes are reported for all levels and comparisons made with those available in the literature. Finally, effective collision strengths are reported for all transitions over a wide temperature range below 10^6^K. Comparisons are made with earlier results and the accuracy of the data is assessed.2008A&A...486.1053Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/486/1053CatalogResearchIsServedByTAP 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)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)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/486/1053https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/486/1053http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/486/1053https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/486/1053https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/486/1053http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/486/1053GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/486/1053/levelsEnergy levels of OIV and their lifetimesrecnoRecord number assigned by the VizieR team.
