Scanned-energy mode photoelectron diffraction has been used to investigate the local structure of N adsorbed on Cu(111). The results favour an N-induced pseudo-(100) reconstruction as proposed previously, but indicate that this comprises two reconstructed Cu layers. The N atoms occupy hollow sites approximately coplanar with the outermost pseudo-(100) layer at a height of about 2 Å above a Cu atom from the underlying pseudo-(100) layer; the N atoms thus have fivefold co-ordination.
