Аннотация:
An unsatisfactory aspect of an earlier low-energy electron diffraction structure analysis of a clean Ag (110) surface has been eliminated by preparing a new surface. The structure of clean Ag (110) was substantially confirmed to correspond to truncation of the bulk crystal but with 10% contraction of the first interlayer spacing. This conclusion was reached both by visual and quantitative (r-factor) evaluation of the correspondence between theory and experiment. Possible explanations of the earlier discrepancies are discussed.
