Surface diffusion of deuterium and hydrogen on Pt(ll1) has been investigated by laser-induced thermal desorption. As the initial surface coverage of deuterium is varied from 0.001 to 0.33, the diffusional activation energy falls from 12 to 7 kcal/mol, and the pre-exponential factor falls from 3 x lo
