Abstract:The self-energy of an electron in a structurally disordered solid is calculated selfconsistently in the single site approximation. Short range order is taken into account by an atom distribution function with sharp peaks. For smooth atom potential form factors a nonlinear system of equations for the self-energy is derived, which can be solved numerically.Die Selbstenergie eines Elektrons in einem strukturell ungeordneten Festkorper wird selbstkonsistent in Ein-Zentren-Nlherung berechnet.
