Abstract

We have measured the Brillouin spectrum of LiF at hypersound frequencies in the [100] and [110] planes. In addition to the longitudinal mode we have observed the pure transverse modes in these planes. Both the polarization and the relevant intensities confirm the assignment. The measured elastic constants are compared with ultrasonic data.
