The interaction of ultrasonic beams in solid media has been investigated from both the theoretical and experimental viewpoint. An error in the previously reported classical calculation has been corrected and relatively good qualitative agreement now exists between the classical and quantum mechanical calculations. Experiments are described which verify certain theoretical predictions concerning the magnitude of interaction and the conditions of resonance. Techniques have been devised for producing interaction in specimens of unusual shape. The feasibility of using interaction techniques in making a three-dimensional analysis of elastic anisotropy has been demonstrated.
