Neutron scattering study of melting ofHe3surface layers

Abstract
The melting of the incommensurate phase of He3 submonolayers adsorbed on Grafoil was investigated by elastic neutron scattering. The temperature dependence of the nearest-neighbor distance, the coherence length, and the peak intensity of the structure factor can be explained by a simple model assuming a melting transition which is driven by thermally created lattice defects.
