cds-question@unistra.fratomic-physicsHelium-like ions provide an important X-ray spectral diagnostics in astrophysical and high-temperature fusion plasmas. An interpretation of the observed spectra provides information on temperature, density, and chemical compositions of the plasma. Such an analysis requires information for a wide range of atomic parameters, including energy levels and transition rates. Our aim is to provide a set of accurate energy levels and transition rates for helium-like ions with Z=10-36. The second-order many-body perturbation theory (MBPT) was adopted in this paper. To support our MBPT results, we performed an independent calculation using the multiconfiguration Dirac-Hartree-Fock (MCDHF) method.2016A&A...592A.141Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/592/A141CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/376/1113 : Line ratios for helium-like ions (Porquet+, 2001)J/A+A/583/A82 : Electron-impact excitation for Hydrogen-like ions (Li+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/592/A141https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/592/A141http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/592/A141https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/592/A141https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/592/A141http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/592/A141GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/592/A141/table2*Wavelengths, transition rates, oscillator strengths and line strengths for transitions among 1snl(n<=6, l<=(n-1)) and 2ln'l(n'<=6, l<=(n'-1)) configurations in helium-like ions with Z=10-36recnoRecord number assigned by the VizieR team.
