A low-energy-electron-diffraction intensity analysis of a clean and annealed {110} surface of Ni3Al reveals that the first layer is 50% Ni-50% Al and that the second layer is 100% Ni. In the first layer, the Ni and Al subplanes are slightly separated from one another by 0.02±0.03 A, the Al atoms being outwards from the bulk. The first interlayer distance, as measured from the Ni subplane, is contracted by 0.15±0.03 A (11.9% of the bulk value, 1.26 A). The second interlayer distance is expanded by 0.04±0.03 A (3% of the bulk value). The r-factor values for normal (0.14) and oblique (0.13) incidence indicate a very good fit of theory to experiment. © 1986 The American Physical Society.
