Abstract
A study of dissociative adsorption/recombinative desorption of O 2 on Ag(111) is presented. Adsorption is performed at high pressure with a mixture containing isotopically labeled 16O 2 and 18O 2 molecules. Desorption is induced using the method of temperature-programmed desorption. The results show that the dissociative sticking probability for 16O 2 is 1.4 times the dissociative sticking probability for 18O 2, independent of coverage. This surprising effect is interpreted as a signature of stretching of the molecule through an activation barrier into a classically forbidden region.
