用微观光学势理论研究核子—核的散射

Study on Many Body Nuclei with the Theory of Microscopic Optical Potentia

用相对论协变的核子－介子场理论（Ｗａｌｅｃｋａ模型），从耦合常数由符合核物质饱和性质决定的有效Ｌａｇｒａｎｇｉａｎ出发，计算了Ｈａｒｔｒｅｅ－Ｆｏｃｋ自能，研究了有限核的光学势，并进一步讨论了不同靶核（１６Ｏ，４０Ｃａ，９０Ｚｒ，２０８Ｐｂ）在不同的入射质子能量（６５ＭｅＶ～８００ＭｅＶ）的弹性散射微分截面与自旋可观测量，并与实验结果进行了分析比较．

An effective Lagrangian which is det ermi ned by the coupling coefficient in conformation of nuclear matter saturation pro perties,is used to calculate the self energy of a nucleon in the nuclear matter ,and the optical potentials of finite nuclei is investigated,based o n Walecka's covariant meson nucleon model.Finally,the elastic scattering data inclu ding the differential cross section and spin observables of different targe t nuclei are analyzed within a large energy regions.
