✦ Synopsis

Abatrac-The

surface of an electropolished Au(lO0) single crystal has been investigated by synchrotron X-ray diffraction. The crystal was examined after having swept the potential into the double layer of the oxide and hydrogen regions. The results show that there is very little change in the surface atomic roughness from the double layer through the oxide region. When cycled into the hydrogen region, where minimal H, production is measured, the surface becomes very rough. No evidence for inducing the (5 x 20) hexagonal reconstruction was observed.
