Abstract The dispersion of the Rayleigh wave on Cu(100) has been measured by high resolution electron energy loss spectroscopy (EELS) throughout the two-dimensional Brillouin zone in the $$\overline {\Gamma M} {\text{ - direction}}$$ . The experimental data can be matched with a nearest neighbour central force model when the force constant between the first and second layerk 12 is stiffened by 20%. However, the data are likewise explained by assuming stress within the surface layer. The stress could arise from a tendency of the surface layer to contract.
