The nuclear-resonance photon-scattering technique was used for studying the temperature dependence between 12 and 295 K of the anisotropy in the scattering cross section from the 7362-keV level in Zn68 using a single crystal of metallic zinc. The anisotropy ratio of the scattering intensities with the beam parallel and perpendicular to the hexagonal planes of Zn was found to increase strongly between 295 and 12 K. This was interpreted in terms of the anisotropic binding of the Zn atoms and was used for deducing the mean-square momenta p2 and p2 of the Zn atoms at 0 K perpendicular and parallel to the hexagonal planes, and the corresponding Debye temperatures FTHETA and FTHETA. When these values were combined with the known values of the zero-point vibrational amplitudes x2 and x2 obtained using the Mössbauer effect, the theoretical lower limit of the uncertainty principle for a metallic solid was found to be reached almost accurately.
