cds-question@unistra.fratomic-physicsThe elastic and electron-capture processes of He+ ions with ground helium atoms are very important for investigating astrophysics. It is essential to have reliable state-selective charge transfer, elastic, transport cross-sections, and the corresponding reaction rate coefficient data, especially for low collision energies. The elastic and non-radiative electron-capture processes in He+(1s)-He(1s2) collisions are investigated employing the full quantum-mechanical molecular orbital close-coupling method. The ab initio adiabatic potentials and coupling matrix elements utilized are obtained by the multi-reference single- and double-excitation configuration interaction approach. The elastic, charge-transfer, and transport cross-sections in the energy range of 0.01-2500eV/amu and the reaction rate coefficient in the temperature range of 10-109K are computed, and good agreements are achieved compared to the available experimental and theoretical results. Shape resonance, Regge, and Glory oscillations are found in the elastic and charge transfer cross-sections in the considered energy region.2023A&A...674A.201Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/674/A201CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/625/A29 : Slow collisions of O6+ with H cross section (Lin+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/674/A201https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/674/A201http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/674/A201https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/674/A201https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/674/A201http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/674/A201GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/674/A201/tablee1QMOCC calculations for total, spin-resolved state-selective charge transfer cross-sections for electron capture to the singlet and triplet states of He(1snl, n=1-3) atom in He+-He collision system.
