Abstract
A model for Al(Si)Mn quasicrystals is proposed. It is characterized by pure quasiperiodic long range order with icosahedral symmetry. The density and concentrations fit to the experimental values. The interatomic distances are compatible with crystallographic data and compare well to the related α phase. A large number of icosahedral clusters (Mackay icosahedra) are present in the modelKeywords
