Abstract：
The antiproton optical potential at intermediate energies is obtained by the multiple scattering theory. The distorted wave of the antiproton is obtained by this optical potential which includes the spin-orbit interaction terms. In the framework of the distorted wave approximation, we discuss the differential cross section and polarization of antiproton-nucleus inelastic scatterings at intermediate energies. the and Pf(θ) of 12(P,P')12C*,2+,3- states at antiproton energies from 180 MeV to 508 MeV are calculated. It is shown that the theoretical results fit the experimental data at E=180 MeV quite well, and the theoretical results of and Pf(θ) at higher energies are predicted.
