The kinetic-energy distribution of H-H fragment pairs arising from dissociative charge-exchange collisions of 5-keV H/sup +//sub 2/ ions was measured using a flight-time-difference method. The spectrum exhibits 13 discrete kinetic energies between 7 and 10.5 eV in the center-of-mass frame of the projectile. Predissociation of the c/sup 3/Pi/sub u/ state by the repulsive b/sup 3/..sigma../sup +//sub u/ state explains most of the structure observed. In addition, evidence is found for predissociation of the e /sup 3/..sigma../sup +//sub u/ state.
