Phys. Rev. Lett. 105, 103202 (2010) [4 pages]Hot Water Molecules from Dissociative Recombination of D3O+ with Cold ElectronsReceived 27 April 2010; published 3 September 2010 Individual product channels in the dissociative recombination of deuterated hydronium ions and cold electrons are studied in an ion storage ring by velocity imaging using spatial and mass-sensitive detection of the neutral reaction fragments. Initial and final molecular excitation are analyzed, finding the outgoing water molecules to carry internal excitation of more than 3 eV in 90% of the recombination events. Initial rotation is found to be substantial and in three-body breakup strongly asymmetric energy repartition among the deuterium products is enhanced for hot parent ions. © 2010 The American Physical Society URL:
