Abstract
Abstract Multiple diffraction experiments have been performed on a microcrystal and a quasicrystal of the Al–Cu–Fe alloy for the purpose of extracting phase information. The microcrystal used in this work is a twinned rhombohedral crystal exhibiting overall icosahedral symmetry. The experiments are performed by rotating the specimen around the scattering vector, (ψ-scans) and by observing the peaks due to the Renninger effect, and the asymmetric features on the wings of the peaks, source of phase information. By fitting theoretical plots to the experimental ψ-scans we conclude, within the resolution limits of this experiment, that the atomic arrangement in a microcrystal seems to be different from that of the corresponding quasicrystal and that the structure may be centrosymmetric. The measurements on the quasicrystal support a previous finding that the structure is not centrosymmetric.
