摘要：

We have used medium-energy ion scattering to study the anisotropy of the disorder at the onset of melting of the Pb(110) surface. For the disorder in the surface plane we find that the effective number of atoms displaced from lattice sites in the [110] direction (along the close-packed rows) is larger than in the [001] direction. In addition we find that the effective number of atoms displaced in the direction normal to the surface is intermediate between those for the in-plane directions.
