Abstract

The semiclassical distorted wave (SCDW) model of nucleon inelastic and charge exchange scattering at intermediate energies is modified to take accurate account of off-the-energy-shell matrix elements of the in-medium [Formula Presented] interaction and explicit account of the exchange of colliding two nucleons, making use of the G matrix parametrized in coordinate representation. The effects of the modification on the double differential inclusive cross sections are discussed for the cases of [Formula Presented] and (p, nx) reactions on [Formula Presented] at 160 MeV. The modification enables the SCDW model to calculate spin observables. The depolarizations in [Formula Presented] at 80 MeV and [Formula Presented] and [Formula Presented] at 160 MeV by one- and two-step processes are calculated, and the result for [Formula Presented] is compared with experimental data. The calculated spin flips in [Formula Presented] and (p, nx) on [Formula Presented] are analyzed in terms of the effects of in-medium modification of the [Formula Presented] interaction and the contributions of individual components of the effective interaction.
