Description

Multiple Bragg diffraction effects have been observed in an Al-Cu-Fe quasicrystal. The experimental data are analyzed by means of a multibeam perturbation theory. Good fits are obtained between experimental and calculated profiles. The feasibility for phase determination of structure factors is demonstrated. It is found that there is no inversion symmetry in Al-Cu-Fe. (orig.)
