摘要：

Diffusion of the atomic clusters over Ni (111) and (100) surfaces is studied by the molecular dynamics simulation. The activation energies of diffusion of the clusters of different sizes are calculated. It is shown, that cluster's atoms migrate over the surface by individual movement instead of collective motion.
