Abstract
The exponent K in the Anderson orthogonality theorem is calculated for a heavy particle having two sites, when the electron scattering on on e site involves n partial waves. K is given in closed expressions for n=1 ... 4. Small and large translations of the scattering center and t he weak scattering are discussed at arbitrary n. The partial wave 1 ca nnot contribute by more than l+(1/2) to K.
