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)

Abstract (Portuguese)

A repulsao Coulombiana G entre os eletrons localizados e itinerantes, introduzida pela teoria de Ramirez-Falicov e Kimball para sistemas de valencia intermediaria e tratada numa nova aproximacao. Encontram-se transicoes descontinuas, mas nao a ocupacao fracionaria dos estados localizados, embora um termo de hibridizacao seja incluido. (Autor)
