Abstract : Light-sound interaction techniques were developed for measuring the velocity of ultrasonic surface waves on single crystal copper. The technique provides a quick and relatively simple way of orienting single crystal samples to within plus or minus 1 degree. Single crystal surface wave attenuation data were related to the magnitude of reflection loss as a function of crystal orientation. Ultrasonic scattering measurements were related to reflectivity data from single crystal and polycrystalline solids. (Author)
