Inelastic O+H collision data

The collisions have been studied theoretically using a previously presented method based on an asymptotic two-electron linear combination of atomic orbitals (LCAO) model of ionic-covalent interactions in the neutral atom-hydrogen-atom system, together with the multichannel Landau-Zener model.

The method has been extended to include configurations involving excited states of hydrogen using an estimate for the two-electron transition coupling, but this extension was found to not lead to any remarkably high rates. Rate coefficients are calculated for temperatures in the range 1000-20000K, and charge transfer and (de)excitation processes involving the first excited S-states, 4s.^5^S^o^ and 4s.^3^S^o^, are found to have the highest rates.
