Abstract
In isotropic solids, transverse acoustic waves propagate undistorted and the interaction of collinear transverse waves is forbidden. We stress here that transverse waves behave differently in anisotropic solids and we give experimental evidence for the interaction of transverse acoustic waves propagating along the threefold axis of a cubic crystal.
