Abstract
The results of X-ray scattering studies of the (111) and (001) surfaces of Au and Pt are summarized. Each of these surfaces exhibits, in some temperature range, a reconstruction which approximates a close packed hexagonal layer, denser than the (111) planes of bulk Au or Pt. The results are discussed in the context of recent theories of surface reconstruction and of two-dimensional phase transformations.
