Two mean-field models describing the metal-insulator phase transition are studied. In the model due to Keldysh and Kopaev (1964) different effective masses in the valence and conduction bands are considered and in the model due to Mattis and Langer (1970) the exact S.C. and b.c.c. densities of state
