Phys. Rev. Lett. 60, 2160–2163 (1988)Speckle in the Diffraction Patterns of Hendricks-Teller and Icosahedral Glass ModelsReceived 17 February 1988; published in the issue dated 23 May 1988 It is shown that the x-ray diffraction patterns from the Hendricks-Teller model for layered systems and the icosahedral glass models for the icosahedral phases show large fluctuations between nearby scattering wave vectors and from sample to sample, that are quite analogous to laser speckle. The statistics of these fluctuations are studied analytically for the first model and via computer simulations for the second. The observability of these effects is discussed briefly. © 1988 The American Physical Society URL:
