Abstract
The tight-binding diagonally disordered Anderson model for a normal metal with a mean-field-Bardeen-Cooper-Schrieffer (BCS) interaction term is solved within the approximation of zero kinetic-energy contribution. The solution with a uniform superconductivity order parameter seems to give good agreement with experimental data in amorphous materials.Keywords
