摘要：

We report on the distributions of valence and conduction states in various crystalline and quasicrystalline alloys. We pay special attention to the distribution of states in the vicinity of the Fermi level. We suggest that the high resistivities observed in particular for quasicrystalline Al-Cu-Fe and Al-Pd-Mn alloys could be the consequence of both the very low Al 3p density of states at the Fermi level and vanishing of the Al p conduction band over a wide energy range beyond the Fermi level.
