Inelastic H+Li and H- + Li+ Collisions and non-LTE Li I Line Formtion in Stellar Atmospheres

Barklem, Paul S; Belyaev, A.; Asplund, Martin


Rate coefficients for inelastic collisions between Li and H atoms covering all transitions between the asymptotic states Li(2s,2p,3s,3p,3d,4s,4p,4d,4f)+H(1s) and Li++H- are presented for the temperature range 2000-8000 K based on recent cross-section calculations. The data are of sufficient completeness for non- LTE modelling of the Li I 670.8 nm and 610.4 nm features in late-type stellar atmospheres. Non-LTE radiative transfer calculations in both 1D and 3D model atmospheres have been carried...[Show more]
