Crossed-beam reaction of O(D-1)+D-2 -> OD+D by velocity map imaging

The technique of velocity map imaging [Eppink and Parker, Rev. Sci. Instrum . 68 (1997) 3477] has been applied to the reaction O(D-1) + D-2 --> OD + D under single-collision conditions in crossed molecular beams at a collision energy (E-coll) of 2.4 kcal/mol. Images of the reactively scattered D-atom product were recorded, yielding the full double differential cross-section s (energy and angle) for the reaction. The translational energy and angular distributions are observed to be strongly coupled, with the forward-scatte red products showing the largest translational energy release and the sidew ays-scattered products the lowest translational energy release.
