High-resolution inelastic He-atom-scattering experiments, employing a time-of-flight energy resolution technique, have been carried out on LiF(001){l_angle}100{r_angle} for a wide range of temperatures and for several different incident beam angles. A quantum-mechanical multiphonon theory is used to explain the observed inelastic background. Numerical calculations based on the theory produce good agreement with experiment.
