    Abstract

    Dissocative electron attachment processes have been observed in O- electron stimulated desorption from multilayer films of N2O molecules condensed on polycrystalline platinum at 30 K. Kinetic energy distributions, fixed kinetic energy O- yields and O- yields are reported. The ion yields show dissociative attachment processes at 9 and 15 eV which are not observed in the O- formation for isolated N2O molecules. The kinetic energy distributions are broad and show that a value of about 0.5 eV is obtained for the most probable kinetic energy of O- ions whatever the incident electron energy. This indicates that the desorption dynamics are driven by the dissociation dynamics of the N2O-* resonant states involved.
