Abstract
This paper presents the first calculations of proton inelastic scattering in which the medium effect of Pauli blocking is included through an exact, rather than angle averaged, operator. This improvement is important in the isoscalar channel at proton energies near 100 MeV and fades as the energy rises. However, processes that emphasize finite-range exchange (such as $0^+\to 0^-$ reactions) still see significant effects at 200 MeV. The results depend on the directions of the incident and struck nucleon momenta that produce the most important contributions to the DWBA integral at each scattering angle.
