Several isointensity contour plots of diffuse scattering around Bragg reflections have been obtained at 300 and 20K on planar sections of reciprocal space perpendicular to twofold axes. The 1/q 2 dependence of diffuse scattering was verified in the neighborhood of the (046046) Bragg reflection, but not near the (533311), a possible indication of lack of equilibrium in the phason fluctuations.
