| Abstract: | MeV He+ ion backscattering has been used to show that the phase transition on a Pt(100) surface involves the lateral displacement of an entire plane of atoms. It is further shown that the outward relaxation of the unreconstructed surface plane is negligible, i.e. 0.5 ± 0.5% of thebulk interplanar spacing. |
