Abstract

We give a method of obtaining the electronic structure of the ground state of intermediate-valence systems by means of a nonlocal potential deduced by the variations of the total energy with the number of f electrons. In addition, we deduce this potential from the Greens function for interacting f systems and we calculate the band structure and the density of states of golden-phase SmS for several values of the energy U and lattice parameters. © 1988 The American Physical Society.
