An approximation is developed to the scattering path operator for a topologically disordered system of muffin‐tin potentials. Using the multiple scattering Green's function formalism a simple expression is obtained for the local density of states (LDOS). A heuristic type of averagingprocedure can be chosen which leads to non‐negative LDOS in the conduction band. Numerical results are presented for an s‐resonance model and for liquid 3d transition metals using a self‐consistent crystalline muffin‐tin potential and experimental pair distribution function.
