• W2083608178 abstract "We apply the technique of specular scattering of energetic beams from carefully flattened surfaces to investigate the dynamics of the O2Ag(111) adsorption/reaction system. The experiments were performed using 100–3000 eV beams of O+2 incident at 85° to the surface normal. The scattering products, O, O2, O− and O−2 were observed using time-of-night techniques. Part of the incident O+2 beam dissociates via charge transfer to dissociative or predissociative states of O2. Charge transfer to the ground electronic state of O2, if accompanied by the transfer of a second electron, results in O−2 formation. Above a threshold energy of 180 eV, the probability of formation of vibrationally cold O−2 is high (> 5%), indicating a large charge transfer probability at the surface and efficient access of the O−2 region of the adsorption/reaction potential energy surface (PES). At an incident beam energy of 2000 eV a threshold for O− production is observed. Classical trajectory calculations performed for the scattering of O2 from Ag(111) indicate that below 2000 eV no dissociation of the molecule occurs and that even about a fraction of a third of the molecules is vibrationally cold. Above 2000 eV collision induced dissociation of the O2 molecule is observed in the calculations that bears a striking resemblance to the experimentally observed O− yield. Therefore we propose that O−2 dissociates as a result of the impulsive collision with the surface, resulting in the observed O− production. We conclude from our results that O−2 is a precursor to dissociative adsorption and that the O− region of the PES is not readily accessible in our experiment, despite the presence of sufficient translational energy to overcome all activation barriers along the reaction coordinate." @default.
