Abstract
Using scanned energy mode photoelectron diffraction we show that in th e potassium-induced reconstruction of the Cu{110} surface the K atoms occupy four-fold hollow sites formed by second layer Cu atoms. This sa me site, which is the key to the reconstruction, is observed both at l ow coverages, where the reconstruction is local in nature, and at cove rages corresponding to the (1 X 3) and (1 X 2) missing row structures.
