Add to ORKGThe degeneracy of the reciprocal space with respect to the icosahedral symmetry has been demonstrated by experimental diffraction patterns obtained from rapidly solidified A1-Mn-Si, Mg-A1-Ag, Mg-AI-Zn alloys. The distortion in diffraction patterns has been attributed to rational approximant (RA)structures. The distorted pattern obtained from Mg-A1-Zn system has been indexed based on 3/2 RA structure. The shift parameter has been quantified and shown to vary linearly with the pseudospace counterpart of the corresponding quasicrystalline reciprocal vector, which is the characteristic feature of phason strain
