【摘要】 本文用基于Walecka模型得到的相对论微观光学势系统地分析了300MeV以下质子一核的弹性散射实验数据,包括微分截面,分辨本领和自旋转动函数.理论计算结果与实验数据很好地符合,在θ<70°范围内较好地符合实验微分截面,并且能给出自旋有关量的细致结构.结果表明这种简单的模型给出的相对论微观光学势适用于各种靶核、E<300MeV的很大能量范围内的核子弹性散射.它可以推广用于核输运理论以及重离子反应中同时考虑核介质与相对论效应.更多还原

【Abstract】 Relativistic microscopic optical potential of a nucleon above the fermi sea based on Walecka’s model is used to systematically analyze the proton elastic scattering from nuclei at energies below 300 MeV. It is shown that the experimental data of differential cross sections, analyzing powers and spin rotation functions are reproduced satisfactorily except for large angles. This simple model might be used in the nuclear transport theory and heavy ion collision to take account of both nuclear medium and relativistic effects.更多还原
