Abstract

We consider the hybridization of atomic and nearly free states in the mixed-valence systems within the procedure which allows to separate in special cases the Hubbard and Fermi branches of elementary excitations. We discuss the physical consequences of this separation and propose a mechanism of phase transition with the valence change where the localized moments of the f-states disappear in the low-temperature phase due to the Mott-Hubbard transition.
