We report the direct formation of H<sub>2</sub> and O pair ions through single collisions of water ions with metal surfaces at hyperthermal energies. This unusual intramolecular reaction proceeds also for heavy and semi-heavy water, producing molecular D<sub>2</sub> and HD ions. The selectivity of this water splitting channel is estimated at being between 9 and 13% <i>versus</i> complete dissociation. The collision kinematics support the hypothesis of a water molecule colliding with a single sur ...[more]
