The elastic constants of cuprous oxide have been measured by a standard pulse echo technique. The low temperature limiting values of the stiffness moduli are (in units of 10 11 dyn/cm 2 ) C 11 = 12.1 ± 0.5, C 12 = 10.5 ± 0.4, C 44 = 1.09 ± 0.03. The Debye temperature calculated from these is 181° K. Both shear moduli show an unusual increase with increasing temperature.
