摘要
运用多次散射理论的光学势获得反质子的扭曲波．在扭曲波冲量近似下，讨论了中能区反质子与原子核的非弹性散射．考虑了反质子能量从１８０ＭｅＶ到１８００ＭｅＶ这一能区１２Ｃ，的２＋，３－态微分截面．在这一能区的低能端，（Ｅ＝１８０ＭｅＶ）ＤＷＩＡ能够很好的符合实验，同时，预示了更高能量可能出现的微分截面的理论结果．
The distorted wave of antiproton is obtained by an optical potential derived from the multiple scattering theory In the framework of the distorted wave impulseapproximation, we discuss the antiproton-nucleus inelastic scattering at intermediate energies. The inelastic differential cross sections of 2+, 3- states at antiproton energies from 180 MeV to 1800 MeV are calculated. It is shown that DWIA fitted the experimented data quite well, and theoretical results of inelastic cross sections at higher energies are predicted.
