Charge transfer of O with H+ at high temperatures

Abstract

We are studying the theory of the charge transfer of atomic oxygen with a hydrogen ion in the velocity range of 400-800 km/s (0.18-0.36 a.u.). There are no previous calculations or experimental results for the differential cross section spanning this energy range. The quantum close-coupling and semi-classical methods were used in these calculations. Using previously published adiabatic potentials and nonadiabatic couplings, the results of cross sections from both methods are of the same order of magnitude as the previous calculations and experimental data. The differential cross sections from our quantal calculations have a peak value that increase with energy and an angular width that decreases with energy, as in previous experimental results
