Abstract
Starting from the Hartree-Fock approximation a general variational ansatz for the ground state of the metal-hydrogen system is presented which properly describes the strong correlation effects occuring at larger distances from the surface. As a simple example the Anderson model is studied. The calculated ground state energies are in excellent agreement with exact model calculations.
