Abstract

The kinetic-energy distribution of H-H fragment pairs arising from dissociative charge-exchange collisions of 5-keV

H_{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 {}^{3}Π_{u}

state by the repulsive

b {}^{3}Σ_{u}^{+}

state explains most of the structure observed. In addition, evidence is found for predissociation of the

e {}^{3}Σ_{u}^{+}

state.
