Here we present the method based on formal solutions of $T$-matrix scattering theory. Within this approach the density of states can be presented as some function of $T$-matrix that describes the scattering processes of electron in the conduction band of disordered metal averaged over configuration. We use weak bond approximation and partial wave approach to get $T$-matrix. We get partial phase shifts from the partial mode of the Lippmann-Schwinger equation for scattered wave function where electron-ion interaction is described by a non-local model potential and we use the Percus-Yevick hard sphere model for the structure factor.
