摘要：
A model pair potential is calculated for Mn-Mn pairs in Al using a Green's function method. The pair potential has a preferred spacing of 4.7 angstrom. The energy resulting from these Mn-Mn interactions strongly favors the Al6Mn, alpha-AlMnSi, and icosahedral quasicrystal structures relative to competing simple structures, providing a possible mechanism for stabilizing the complex structures.
