X-ray diffraction from single Al₆CuLi₃ grains showing five-fold symmetry

Abstract

We present here the detailed results of X-ray diffraction from single quasicrystals of Al₆CuLi₃. X-ray precession photographs taken down the two-, three- and five-fold axes along with rotation and zero-level Weissenberg photographs are shown. Preliminary analysis of the diffraction data rules out the twin hypothesis.
