Clean and O-adsorbed (113) surfaces were studied by means of scanning tunnelling microscopy at room temperature. It was found that clean surfaces reconstructed into a (1 x 2) missing-row structure. Significant faceting was observed in the initial stages of annealing at 1150K. However, wider (113) terraces were found after annealing for longer times. Following the adsorption of atomic O, protruding atomic rows which ran in the [¯110] direction were separated by many dark nodes. The intervals of the nodes ranged from 0.6 to 0.9nm. This corresponded to 2 or 3 times the atomic distance along the rows; thus suggesting that O atoms were adsorbed at those intervals.
