Molekularstrahlexperiment der Reaktiven Streuung D+H2 Yields HD+H (Molecular Beam Experiment of the Reactive Scattering D+H2 Yields HD+H)

摘要

The reaction D+H2 yields HD+H was investigated in a molecular beam at a translational energy 1.0 eV, scanning the potential hypersurfaces in the same energy domain as the reaction of vibration-excited hydrogen molecules. Angular and product velocity distributions of the reactions were determined. The differential scattering cross section at high collision energies is found to be strongly broadened compared with calculations and experiments at lower energies. The measured angular and time-of-flight distributions can satisfactorily be fitted with quasiclassical trajectory data calculated on potential hypersurfaces. The HD angular distribution is described with a model calculation. This calculation describes a narrower product velocity distribution (angle independent) in contrast with a more accurate theory.
