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-原子核反应：核子-核子相互作用的激发与进入质子的原子核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。将其应用于微分截面的实际累积。我们还研究了在洛斯阿拉莫斯得到的自旋响应函数。实验再现了表面密度效应，即自旋混合效应和纵向-横向自旋混合效应。反质子-微束反应：从弹性散射数据推导出50 Mev p的光学势。由此产生的电位具有很强的虚气。我们还注意到（p,n）与Cercade双粒子介子-核反应的结合：证明介子的分类是通过三体过程发生的，而不是两体过程在δ等能级区。发现形体过程很小。（<pi^+>, <pi^->）的反应是用DINT和DSEQ数据等压差计算的。实验数据不能被复制。我们必须考虑高利率项。重离子-核反应：用簇模型波函数在微观上计算了Pioni聚变截面。用该模型再现了实验特征。高能重离子碰撞数据的计算采用核级联模型，该模型具有较好的适用性。
