The electronic density of states is calculated from the incident‐field amplitudes of a multiple scattering problem based on a muffin‐tin model. Using the idea of Haydock's LCAO recursion method, the multiple scattering between atomic angular‐momenturn channels is replaced by multiple scattering between incident‐field distributions of decreasing local relevance. The proposed method is tested numerically for a cluster of 13 nickel atoms.
