Popis:	Low energy electron diffraction and low energy ion scattering observations on Cu3Au(110) reveal a correlation between surface compositional ordering and the average compositions in the first and second surface atom layers. The surface undergoes a broadened, discontinuous 2 × 1 → 1 × 1 transition at least 6 K below the bulk compositional-disordering transition at 660 K, while near 660 K the values of Au atom fractions in the first (second) atom layers approach 0.35 (0.35) starting from 0.45 (0.20) below 400 K.
