cds-question@unistra.fratomic-physicsplanetary-nebulaeWe calculate effective recombination coefficients for the formation of the 5g-4f lines of O III in the intermediate coupling scheme. Photoionization data for the 5g levels calculated using the R-matrix method are used to derive their recombination coefficients. Cascading from higher states is included, allowing for the effects of finite electron density in a hydrogenic approximation. We explicitly include the distribution of population between the two ground levels of O^3+^ in the calculation of the line intensities. The results are presented as a simple programmable formula allowing the calculation of recombination line intensities for electron temperatures, T_e_ in the range 5000-20000K and electron densities, N_e_ in the range 10^2^-10^6^cm^-3^.1999A&AS..137..157Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/137/157CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/133/257 : Recombination coefficients for NeII lines (Kisielius+ 1998)J/A+AS/135/359 : HI and HeII fine structure components (Clegg+ 1999)J/A+AS/142/85 : Recombination coefficients for C II lines (Davey+, 2000)J/A+A/387/1135 : NII effective recombination coefficients (Kisielius+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/137/157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/137/157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/137/157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/137/157https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/137/157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/137/157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/137/157/table1Indices n_1_ and energy levels of the 4f and 5g states in O^2+^ ionsrecnoRecord number assigned by the VizieR team.
