Abstract
The correlated Kondo-lattice model is used to describe the interaction of electrons in a single conduction band with localized magnetic moments as well as their mutual repulsion. It is our intension to provide an analytical exact result for this model by considering a two-site cluster. An equation-of-motion approach as well as the spectral theorem is chosen to obtain the complete expression for the one-particle Green's function. In a forgoing article the problem has been solved for an insulator, the present paper is devoted to the technical more demanding task of a metal.
