Molecular beam measurements of differential cross sections for the reaction D+H2→HD+H at E=1.0 eV

Abstract

The angular and velocity distributions of HD formed in the cross molecular beam reaction D+H2 have been measured at an effective center-of-mass energy of 1.0 eV. The results are compared with calculations based on quasiclassical trajectories for the Siegbahn–Liu–Truhlar–Horowitz potential. The calculations are in reasonable agreement with the experiment, which probes the potential energy surface at 0.85 eV in the repulsive saddle point region.
