cds-question@unistra.frEffective recombination coefficients are given for C II transitions between doublet states. The calculations are carried out in the temperature range 500-20000K and for an electron density of 10^4^cm^-3^. The effects of electron collisions on the excited states are included. The necessary bound-bound and bound-free radiative data are obtained from a new R-matrix calculation in which photoionization resonances are fully delineated, thereby accurately incorporating the effects of both radiative and dielectronic recombination. The R-matrix calculation includes all bound states with principal quantum number n<=15 and total orbital angular momentum L<=4. The effect of moving the resonance features to their experimentally determined positions is also investigated and found to be important at low temperatures.2000A&AS..142...85Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/142/85CatalogResearchIsServedByTAP 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/137/157 : O III recombination coefficients (Kisielius+, 1999)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/142/85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/142/85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/142/85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/142/85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/142/85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/142/85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/142/85/table1Energies of even parity C^+^ bound states relative to the ionization thresholdrecnoRecord number assigned by the VizieR team.
