cds-question@unistra.fratomic-physicsData for inelastic processes due to hydrogen atom collisions with iron are needed for accurate modelling of the iron spectrum in late-type stars. Excitation and charge transfer in low-energy Fe+H collisions is studied theoretically using a previously presented method based on an asymptotic two-electron linear combination of atomic orbitals model of ionic-covalent interactions in the neutral atom-hydrogen-atom system, together with the multi-channel Landau-Zener model. An extensive calculation including 166 covalent states and 25 ionic states is presented and rate coefficients are calculated for temperatures in the range 1000-20000K. The largest rates are found for charge transfer processes to and from two clusters of states around 6.3 and 6.6eV excitation, corresponding in both cases to active 4d and 5p electrons undergoing transfer. Excitation and de-excitation processes among these two sets of states are also significant.2018A&A...612A..90Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/612/A90CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/572/A103 : Inelastic silicon-hydrogen collision data (Belyaev+, 2014)J/A+A/587/A114 : Inelastic calcium-hydrogen collision data (Belyaev+, 2016)J/A+A/593/A27 : Inelastic beryllium-hydrogen collision data (Yakovleva+, 2016)J/A+A/606/A11 : Inelastic e+Mg collision data (Barklem+, 2017)J/A+A/606/A106 : Inelastic manganese-hydrogen collisions data (Belyaev+, 2017)J/A+A/606/A147 : Heavy particle-hydrogen collisions (Belyaev+, 2017)J/A+A/608/A33 : Inelastic manganese-hydrogen collisions data (Belyaev+, 2017)J/A+A/610/A57 : Inelastic O+H collision data (Barklem, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/612/A90https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/612/A90http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/612/A90https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/612/A90https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/612/A90http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/612/A90GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/612/A90/table1Input data for calculations; full table 1recnoRecord number assigned by the VizieR team.
