摘要: Preliminary results are reported on the inelastic scattering of low-energy (20 meV), monoenergetic ($\frac{\ensuremath{\Delta}v}{v}=0.8%$ full width at half maximum) He nozzle beams from a LiF(001) surface along $〈100〉$ direction. The time-of-flight spectra reveal both broad and extremely sharp maxima. maxima attributed to distribution phonons bulklike character with small momenta, while indicate excitation single discrete modes.
