cds-question@unistra.fratomic-physicsThe level-resolved radiative recombination (RR) rate coefficients for H-like to Na-like ions from H (Z=1) up to and including Zn (Z=30) are studied here. For H-like ions, the quantum-mechanical exact photoionization cross sections for nonrelativistic hydrogenic systems are used to calculate the RR rate coefficients under the principle of detailed balance, while for He-like to Na-like ions, the archival data on ADAS are adopted. Parameterizations are made for the direct capture rates in a wide temperature range. The fitting accuracies are better than 5% for about 99% of the ~3x10^4^ levels considered here. The ~1% exceptions include levels from low-charged many-electron ions, and/or high-shell (n>~4) levels are less important in terms of interpreting X-ray emitting astrophysical plasmas. The RR data will be incorporated into the high-resolution spectral analysis package SPEX.2016A&A...587A..84Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/587/A84CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/587/A84https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/587/A84http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/587/A84https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/587/A84https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/587/A84http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/587/A84GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/587/A84/rr_spex3Fitting parameterszAtomic numberphys.atmol.numberintLAngular momentum quantum number, Lphys.atmol.qnintrecnoRecord number assigned by the VizieR team.
