Nuclear<i>γ</i>-ray resonance observations in an aluminum-based icosahedral quasicrystal

Abstract

Nuclear \ensuremath{\gamma}-ray resonance (M\"ossbauer effect) results are presented from rapidly solidified Al-(Mn,Fe) alloys which contain the orientationally ordered phase with icosahedral point-group symmetry. Detailed analysis of the spectra obtained is consistent with an icosahedral quasicrystalline model for the structure of this phase.
