ResumoEnergy losses accompanying the detachment of an electron from Cl− in collision with H2 and D2 have been measured using a time-of-flight technique. Four different energy loss channels are identified and their excitation functions mapped: (1) ΔE?4 eV corresponding to ’’simple detachment’’ (E.A. Cl−=3.6 eV); (2) ΔE?8 eV corresponding to dissociative attachment; (3) ΔE ranging from 11 eV at Erel?15 eV to 14 eV at Erel?50 eV associated with detachment to the 2Σ+g state of H−2; (4) ’’spectator’’ backscattering from a single hydrogen atom.
