Double-differential studies of the fast neutrals (Cl) resulting from collisional detachment of Cl/sup -/ on N/sub 2/ (E/sub lab/< or =300 eV) show energy-loss peaks at 6 and 12 eV. It is noteworthy that a high-loss peak is dominant at low E/sup theta/. Similar studies of the inelastically scattered Cl/sup -/ reveal significant vibrational-rotational exictation of N/sub 2/ but no electronic excitation of the N/sub 2/ is observed. Arguments are presented which support the hypothesis that the known negative-ion resonance of N/sub 2/ are involved in the detachment processes.
