Using X-ray precession method,it is found that the distribution of reciprocal lattice ofβ-W structure is lust the distortion of the reciprocal space of A16Li3Cu quasicrystal structure.Except the distortion,the X-ray diffraction patterns along 5-fold,3-fold and 2-fold axes can be observed.Their angular relations satisfy well with those of the perfect icosahedral symmetry;and all the diffraction spots can be indexed approxmately to be six-dimension and strictly in three-dimension.
