Abstract
The local atomic structure of the Ag induced surface has been investigated using photoelectron diffraction (PED) at 10 and . Two surface components, whose intensities varied by changing the photon energy as a consequence of diffraction effects, were observed in the core-level spectra at both temperatures. The good agreement between the experimental PED patterns of the surface components and the simulated PED patterns indicates that the atomic structure of this surface follows the inequivalent triangle model. Further, since the PED patterns obtained at 10 and resemble each other closely, we conclude that the local atomic structure of the surface is the same at the two temperatures, and thus that the origin of the transition reported in the literature is an order-disorder transition.
