摘要：
With respect to Anderson localization the interacting electron system in disordered alloys AxB1-x is examined within the random Hubbard model by means of an analytical mean field treatment. The density of states is calculated in the dilute limit, i.e. x --> 0. Extensive results are presented about the interplay of electron-electron interaction and disorder. Comparison with other theoretical results are discussed.
