Abstract

The analysis of some recent time-of-flight spectra reported by Doak for He inelastic scattering from LiF(001) along the 〈110〉 azimuth reveals important contributions from bulk longitudinal acoustic (LA) phonons. The large intensity due to LA phonons compared to that due to Rayleigh waves is shown to be the result of resonance enhancement. The independent determination of the coupling to LA phonons and to Rayleigh waves permits an estimate of the atom-surface, potential softness. © 1983 Springer-Verlag.
