A method is given for obtaining the electronic structure of the systems which present strong correlated bands arising from different orbitals, for instance f and d. This is performed by means of a non‐local potential deduced from the Green function of the interacting system. In addition, this method is applied to γ‐CeAl 2 and the results agree reasonably with available experimental results.
