Abstract
The diffusion in premelting films and surfaces is described by the Fok ker-Planck equation with a periodic potential whose amplitude depends on the temperature and vanishes at the bulk melting temperature. The s elf-part of the dynamic structure factor is calculated and the results are compared with neutron scattering data from CH4 premelting films a dsorbed on MgO and with atom scattering data from the (110) surface of Pb.
