用微观光学势理论研究核子—核的散射

用相对论协变的核子－介子场理论,从耦合常数由符合核物质饱和有产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在不同的入射质子能量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。

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

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.
