摘要

The charge transfer reaction of Ar+ with H-2 and D-2 has been investigated in an experiment combining crossed beams with three-dimensional velocity map imaging. Angle-differential cross sections for two collision energies have been obtained for both neutral species. We find that the product ions are highly internally excited. In the reaction with H-2, the spin-orbit excited Ar+ state's coupling to the "resonant" vibrationally excited product H-2(+) (upsilon = 2) dominates for both investigated energies, in line with previous investigations. The observed angular distributions, however, show significantly less back-scattering than was found previously. Furthermore, we discovered that the product ions are highly rotationally excited. In the case of Ar+ reacting with D-2, the energetically closest lying vibrational levels are not strictly preferred and higher-lying vibrational levels are also populated. For both species, the backward-scattered products show higher internal excitation. Published by AIP Publishing.
