Abstract

The excitation function for the reaction, O(3P)+H2→OH+H, was studied with accurate quantum wave packet calculations, and the theoretical excitation function was compared with an experimental relative excitation function obtained from a crossed beams experiment employing a novel hyperthermal O-atom beam source. Results lead to the conclusion that the detected OH signal is the result of O(3P) reacting with H2. Further quasiclassical trajectory (QCT) calculations yielded the excitation function for the reaction, O(1D)+H2→OH+H, and allow an upper limit of 1.0 percent to be placed on the fraction of O atoms in the beam that are in the excited O(1D) state.
