    Abstract

    The scattering, from powder and single crystal samples, appears only above the superionic transition temperature, 1000K. The integrated intensity is found to be strongly dependent on the direction and magnitude of the scattering vector, Q, (which suggests the scattering is coherent) but does not exhibit the periodicity of the reciprocal lattice. The energy width of 0.6-1.5 MeV (FWHM) is found to be only weakly dependent on Q, and almost independent of temperature, suggesting that the scattering is more complex than a direct result of the translational motion of the anions. A direct connection with the degree of disorder of the system and the intensity of the scattering is indicated
