Abstract
A general method is presented for determining the wave functions of the conduction electrons in noble metals containing point defect complexes consisting of interstitials, vacancies, and impurities. The wave functions are determined by an integral equation derived from the Hartree-Fock equation. An approximation scheme is developed for solving the integral equation taking into account the multiple scattering arising from the interacting point defects and the scattering by the lattice distortion associated with the point defects. The conduction electron density is derived in general form. The derived wave functions and the electron density can be used for a calculation of the interaction energy of point defects and the electric field resulting from the conduction electron redistribution.
