Coherent scattering in a random-network model for amorphous solids

Coherent scattering regions of approximately 10-25 A in size have been observed in a variety of amorphous solids. It has been suggested that these observations provide evidence for the microcrystalline model. In this note we show that the observations of coherently scattering regions are not incompatible with a random-network model. © 1972 The American Physical Society.
