Abstract
Low-energy ion scattering spectroscopy is used to; obtain real space surface imaging of the atomic surroundings of different fcc metal surfaces. Scattered He+ ions were mapped over a large solid angle sector. By using an universal shadow cone expression. it is possible to invert the angular maps into two-dimensional real space maps. The inversion procedure is tested on Pt(111). Cu(001) and Al(III) surfaces getting nearest neighbour atoms up to a distance of 4 Angstrom. Furthermore, The known surfaces the maps also allow to extract information on the scattering mechanism itself. (C) 1997 Elsevier Science B.V.File in questo prodotto:
