摘要：

The adiabatic motion of a finite chain of atoms interacting in accordance with next-neighbour harmonic forces and placed in a periodic external potential (the Frenkel-Kontorova model) is investigated. The conditions are determined where the activation energy of the chain motion is lower than that of the motion of a single atom. The results are used to explain some experimental data on surface diffusion in chemisorbed systems. © 1990.
