Description
The Coulomb repulsion G between localized and conduction electrons, introduced by the Ramirez-Falicov and Kimball theory for intermediate valence systems has been treated in a new approximation. A discontinuous transition was found, but no fractional occupation of the localized states, although an hybridization term was included. (Author)
