Three-Body Breakup Dynamics in Dissociative Recombination

Using the CRYRing Facility in Stockholm Coupled with an MCP-CCD detector, and a differential stopping foil, we have determined dynamic parameters in the three-body dissociative recombination of H 2 O + . These include the distribution between the O( 3 P) and O( 1 D) channels, the distribution of H atom recoil energies in the O( 3 P) channel and the distribution of angles between the two departing H atoms.
