The technique of orthogonality scattering states is used to examine the effects of antisymmetrization on the first-order nucleon-nucleus optical potential without the assumption of infinite nuclear matter. The required matrix elements of the effective nucleon-nucleon scattering operator contain a Pauli distortion of the continuum states. This effect is approximated as a Pauli distortion of the effective nuclear density that arises in a factorization prescription, and the influence of this on scattering is estimated.
