Abstract

A model is deduced for the electronic structure of the Ce systems. It includes a pseudopotential which considers the strong correlation effects due to the fluctuation of the number of f‐electrons in the Ce atoms. The pseudopotential affects the f‐symmetries according to their own occupations and is different from zero when the f‐states are spd/f hybridized. The APW method is modified in order to introduce the pseudopotential within the band structure Hamiltonian. Finally, the so‐called „three‐peak” 4f structure which appears in the Ce systems is analyzed with our model. Copyright © 1986 WILEY‐VCH Verlag GmbH & Co. KGaA
