    Scattering of low-energy (5-12 eV) C2D4.+ ions from room-temperature carbon surfaces

  • Original language description

    The scattering of the hydrocarbon radical cation C2D4 center dot+ from room-temperature carbon (highly oriented pyrolytic graphite, HOPG) surface was investigated at low incident energies of 6-12 eV. Mass spectra, angular and translational energy distributions of product ions were measured. From these data, information on processes at surfaces, absolute ion survival probability, and kinematics of the collision was obtained. The projectile ion showed both inelastic, dissociative and reactive scattering,namely the occurrence of H-atom transfer reaction with hydrocarbons present on the room-temperature carbon surface. The absolute survival probability of the ions for the incident angle of 30 degrees (with respect to the surface) decreased from about 1.0%(16 eV) towards zero at incident energies below 10 eV.

    Rozptyl pomalých (5-12 ev) iontů C2D4+ na uhlíkovém povrchu při pokojové teplotě

  • Czech description

    Rozptyl uhlovodíkového radikálkationtu C2D4+ na povrchu uhlíku (vysoce orientovaný pyrolytický grafit, HOPG) za pokojové teploty byl sledován při malých energiích dopadu 6-12 eV. Byla měřena hmotnostní spektra, uhlová rozdělení a rozdělení translační energie iontových produktů. Z tšchto dat byly odvozeny informace o procesech u povrchu, absolutní hodnoty přežití iontů, a kinematika srážkových procesů.
