(He,H2+) dynamics revisited

摘要

The differential cross section for the backward and the forward scattering of the product in (He,H2+) collisions and its dependence on reagent vibration and translation as determined by a three dimensional quasiclassical trajectory study are shown to be in accord with the recently reported experimental results. An investigation of the role of reagent rotation on the differential and integral cross sections for the reaction He+H2+rarr;HeH++H and also on the branching ratio for the two isotopic channels in He+HD+rarr;HeH++D; HeD++H reveals that the dynamical attributes are not strongly dependent on the initial rotational state of the diatom as there is no preferred geometry for the reaction.
