Excitation and charge transfer in low-energy hydrogen atom collisions with neutral oxygen

Barklem, P. S. Excitation and charge transfer in low-energy O+H collisions is studied; it is a problem of importance for modelling stellar spectra and obtaining accurate oxygen abundances in late-type stars including the Sun. The collisions have been studied theoretically … Continue reading
