摘要：

This paper reports on He-atom scattering measurements performed in order to shed light on the equilibrium morphology of the bare Ag(110) surface. Measurements of the specular peak profile along [1 (1) over bar 0] and slightly off the out-of-phase scattering condition show that the proposed ''hill and valley'' configuration is originated by thermally induced segregation of bulk impurities. Proper cleaning procedure is described to obtain the unfaceted surface which is proven to be the equilibrium morphology of Ag(110).
