Structure refinement of a water quenched alloy of Al72Ni20Co8, which is known as a highly ordered decagonal quasicrystal, has been carried out by quantitative comparison of experimental and simulated intensities of convergent-beam electron diffraction (CBED) patterns. In the present study, higher-order Laue zone reflections, whose intensities are sensitively changed with atom positions, have been used for the refinement of atom position parameters in the quasiperiodic directions. The refined parameters have been compared with the results obtained by X-ray diffraction.
