## 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 N-N 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 (p,p′x) and (p,nx) reactions on ^{90}Zr at 160 MeV. The modification enables the SCDW model to calculate spin observables. The depolarizations in ^{58}Ni(p,p′x) at 80 MeV and ^{90}Zr(p,p′x) and ^{90}Zr(p,nx) at 160 MeV by one-and two-step processes are calculated, and the result for ^{58}Ni(p,p′x) is compared with experimental data. The calculated spin flips in (p,p′x) and (p,nx) on ^{90}Zr are analyzed in terms of the effects of in-medium modification of the N-N interaction and the contributions of individual components of the effective interaction.
