The nucleon final-state interaction in electron-nucleus quasielastic scattering is studied. Based on the unitarity equation satisfied by the scattering-wave operators, a doorway model is developed to implement the Pauli-blocking of nucleon knockout. The model is complementary to the commonly used nuclear Fermi gas model which can not be applied with confidence to light- and medium-mass nuclei. Pauli blocking in these latter nuclei is illustrated with the case of Coulomb interaction. Significant effects are noted for beam energies below {approx} 350 MeV/c. Extension of the model to high-energy hadron-nucleus quasielastic scatterings is discussed.
