Abstract
The method of glancing-incidence x-ray diffraction has been applied to the Au(110) reconstructed surface. The long-range structure is incommensurate with the bulk in one direction, comprising locally 2 × 1 regions separated by domain walls. The atomic positions in the 2 × 1 cell are determined independently of any models, and their alignment with respect to the bulk is deduced; the result is a missing-row structure with lateral pairing displacements in the second layer of 0.122± 0.017 Å.Keywords
