cds-question@unistra.fratomic-physicsEmissivities have been calculated for fine-structure components of selected UV and optical recombination lines of HI and HeII. Results are given for a range of electron temperatures and densities, and in Cases A and B of Baker & Menzel (1938ApJ....88...52B). Relative intensities, wavelengths and velocity shifts of the fine-structure components are tabulated. Applications to the spectra of gaseous nebulae are discussed. Depending on the temperature, density and Case, the centres of unresolved lines can shift by up to 0.9km/s for HI and 3.3km/s for HeII. A new calibration of the H{alpha}-NII method for determining electron temperatures is given.1999A&AS..135..359Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/135/359CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/64 : Recombination line intensities for hydrogenic ions (Storey+ 1995)J/A+AS/133/257 : Recombination coefficients for NeII lines (Kisielius+ 1998)J/A+AS/137/157 : O III recombination coefficients (Kisielius+, 1999)J/A+AS/142/85 : Recombination coefficients for C II lines (Davey+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/135/359https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/135/359http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/135/359https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/135/359https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/135/359http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/135/359GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+AS/135/359/table1Summary of components, and the reference wavelengths of hydrogenic transitionsrecnoRecord number assigned by the VizieR team.
