Abstract：
Under the distorted wave impulse approximation, we discuss the antiprotonnucleus charge exchange reaction A(p,n)B and the inelastic scattering ACalculations are presented for the differential cross sections of ¹²C(p,n)¹²B,¹⁸O(p,n) ¹⁸N and ¹⁸O(p,n)¹⁸O at antiprotion energies 179.7MeV and 46.8MeV. Distorted wave functions are calculated by the exact partial wave method. It is shown that the theoretical inelastic scattering results fit the experimental data quite well. The theoretical resultes of the diferential cross sections for antiproton-nucleus charge exchange reactions are also predicted.
