Predissociation of the c /sup 3/PI/sub u/ state of H/sub 2/

Journal Article · · Phys. Rev. Lett.; (United States)
A flight-time-difference method was used to measure the energy distribution of H--H fragment pairs arising from dissociative charge-exchange collisions of H/sub 2//sup +/ ions. The spectrum exhibits sharp peaks which coincide with the energies of vibrational levels of the c/sup 3/PI/sub u/ state of H/sub 2/ above the dissociation limit of the ground state. Predissociation into the b/sup 3/..sigma../sub u/ state is the main decay channel of the c/sup 3/PI/sub u/ state. The lifetime is estimated to be < or = 10/sup -8/ sec. (AIP)
