A structural model is proposed for the metal‐amorphous Ge systems, based on the filling of the inner voids by the metal in a tetrahedral CRN. This starting model is relaxed under a set of bond‐stretching, bond‐bending, and Me‐Ge interaction potentials, for the specific case of the Cu x (a‐Ge) 1− x alloys ( x = 0.22 and 0.40). A good agreement between the calculated and an experimental interference function is obtained by assuming an alteration of the bonding character in the a‐Ge matrix towards a more metallic one.
