Abstract：
The distorted wave of anti-proton is obtained by an optical potential derived from the multiple scattering theory. In the framework of the distorted wave impulse approximation, we discuss the antiproton-nucleus inelastic scattering at intermediate energies. The inelastic differential cross sections of ¹²C(p,p')¹²C^*,2⁺,3^- states at anti-proton energies from 180 MeV to 1800 MeV are calculated. It is shown that DWIA fitted the experimental data quite well, and theoretical results of inelastic cross sections at higher energies are predicted.
