The influence of electron collisions on non-LTE Li line formation in stellar atmospheres

Osorio, Y; Barklem, Paul S; Lind, Karin; Asplund, Martin


The influence of the uncertainties in the rate coefficient data for electron-impact excitation and ionization on non-LTE Li line formation in cool stellar atmospheres is investigated. We examine the electron collision data used in previous non-LTE calculations and compare them to our own calculations using the R-matrix with pseudostates (RMPS) method and to other calculations found in the literature.
