Popis:	The sound velocities for longitudinal and transverse waves in single-crystalline CuGeO3 have been measured using ultrasonic pulse-echo and Brillouin scattering techniques. The nine independent elastic constants have been determined. The elastic properties of this material are strongly anisotropic with an order-of-magnitude difference between the longitudinal elastic constants along the c- and b-axes.
