Results on the scattering and the dissociative sticking of O2 molecules on the Ag(110) surface are presented. The dependence on the incidence energy and angle of the molecules is investigated by employing molecular beam techniques. Both the angle with respect to the surface normal and that with respect to the <110> azimuthal direction on the surface are varied. The <110> and <001> azimuthal directions display a different corrugation as observed by the incident molecule. Dissociative sticking is observed to proceed via the molecular chemisorption state and is strongly enhanced by the incidence energy. An azimuthal dependence of the sticking is observed. Results on the desorption of O2 from the Ag(110) surface are also given.
