Abstract: A new approach to Brownian motion of atomic clusters on solid surfaces isdeveloped. The main topic discussed is the dependence of the diffusioncoefficient on the fit between the surface static potential and the internalcluster configuration. It is shown this dependence is non-monotonous, which isthe essence of the so-called resonant diffusion. Assuming quicker inner motionof the cluster than its translation, adiabatic separation of these variables ispossible and a relatively simple expression for the diffusion coefficient isobtained. In this way, the role of cluster vibrations is accounted for, thusleading to a more complex resonance in the cluster surface mobility.
