Annotation
Diffusion of gold nanoclusters on a graphite substrate is discussed. We propose a solution to the contradiction between the extremely high value of the diffusion coefficient and its Arrhenius-type temperature dependence. The possibility of applying the Fermi acceleration model to this problem is shown.
