Abstract

We studied the dissociation of molecular oxygen adsorbed on Ag(110) by electron-energy-loss spectroscopy. We observe that the dissociation of the adsorbed molecules at 150 K is connected to increased surface disorder. The elastic reflectivity is recovered at 200 K independently of coverage when the added row reconstruction of the substrate sets in.
