Abstract：
In the framework of the distorted wave impulse approximation,we discuss the antiproton nucleus inelastic scattering.Calculations are preuented for the ¹²C(p,p)¹²C, 2⁺ and 3⁺ states at antiproton energies of 46.8 and 179.7MeV.Distorted waves are calculated by exact partial wave calculation.It is shown that the DWIA is quite good for the low energies.The importance of the behaviour of bound state wave function is discussed.Due to the strong absorption of antiproton by nucleus,the use of exact bound state wave function is essential.
