24. Fig. 9 depicts one of the rare cases where the reconstruction nucleates on a flat and apparently clean part of the surface. Usually, the hexagonal superstructure starts to develop at surface imperfections such as step edges (Fig. 1) or dislocations.

26. In this experiment, the (111) surface of a gold single crystal was probed in situ by thermal helium atom scattering. Specular helium reflection showed no sign of oxygen adsorption and no diffraction signature corresponding to a (√3 × √3)R30° or any other oxygen-induced surface structure could be detected by LEED or helium diffraction.
