The adiabatic elastic constants of zinc single crystals have been measured by an ultrasonic pulse technique. The values extrapolated to 0^ are: c₁₁=1. 770, c₃₃=0. 685, c₄₄=0. 459, c₁₂=0. 348, c₁₃=0. 528 in units of 10^12 dynes/cm^2. A Debye characteristic temperature, , of 327⁵^ has been calculated at 0^ by averaging the inverse cube of the longitudinal and transverse elastic wave velocities over all directions of propagation.
Garland et al. (1958) studied this question.
