摘要：

Impulsive stimulated light scattering has been used to measure surface wave power spectra of germanium single crystals. In addition to the familiar Rayleigh and pseudosurface acoustic waves, the spectra contain a feature with the directional dependence of the quasilongitudinal bulk wave. Comparisons are presented between measured and calculated spectra. The observed power spectra are found to contain sufficient information to determine all the elements of the elastic tensor.
