Explanation of peak shapes observed in diffraction from icosahedral quasicrystals

The distinctive peak shapes observed in diffraction studies of the icosahedral phases of Al--Mn, Al--Li--Cu, and related alloys are shown to arise from a specific configuration of quenched phason strains in a grain. This configuration is determined by considerations of symmetry and continuity of the...
