项目摘要

Proton-nucleus reaction: The nucleon-nucleon interaction for excitation of a nucleus with incoming proton differ from that in free space. We construct the effectiue interaction by calculating the G-matrix,which includes the Pauli affect. Wo than apply it for actual cdleulation of differential cross section. We study also the spin response functions obtained at Los Alamos. The experiment is reproduced by the surface dansity effect , is:spin-mixing and longitudinal-transverse spin mixihg effects.Antiproton - micleus reaction : We darive the optical potantial for 50 Mev p from the elastic scattering data. The resulting potential has strong imaginary pant. We celeulete also to (p,n) rcection with the Cercade urodelPion-nucleus reaction: Pion assorption is demonstration to accur Through the Thrie body process in adelition to the two body process in the delta isoban energy region. The form body process is found small. ( <pi^+> , <pi^-> ) veaction is calculated with the DINT and DSEQ dalta isobav prscessis. The experimental data is not reproduced by The preceses. We nud to consider the high crder term.Heavy ion-nucleus reaction: Pioni fusion cross section is calculated microscopically by using the cluster vrodel wave functions. The experimatal fcature is repreduced with the model. The high eusgy heavy ion collision data are calculated by the nucleor cascade model,which worlss extenely well.

质子-核反应：用入射质子激发原子核的核子-核子相互作用不同于自由空间中的相互作用。我们通过计算包含泡利效应的G矩阵来构造有效相互作用。并将其应用于不等截面的实际计算。我们还研究了在洛斯阿拉莫斯获得的自旋响应函数。实验重现了表面丹尼斯效应，即自旋混合效应和纵向-横向自旋混合效应。反质子-胶束反应：我们从弹性散射数据中得到了50 MeVp的光学势。由此产生的势具有很强的想象力。我们还用Cercade urodelPion-原子核反应对(p，n)反应进行了研究：π介子的分类是通过Thrie体过程证实的，它与三角洲等压能区的两体过程相一致。发现形体过程很小。(&lt；pi^+&gt；，&lt；pi^-&gt；)veaction用dint和dseq dalta isobav prscessis计算。实验数据不能按程序重现。重离子-核反应：用团簇Vrodel波函数在微观上计算了Pioni核聚变截面。用该模型再现了实验特性。用核级联模型计算了高能重离子碰撞数据，该模型具有较好的普适性。
