论文摘要
我们使用在Ginocchio开发的电位上构成的现象学核核核核能来研究库仑屏障附近不同核系统的弹性分布。研究了针对系统$^{14} $ n+$^{56} $ fe和$^{14} $ n+$^{90} $ zr的弹性与卢瑟福的差分横截面比率。我们的理论预测与实验数据具有良好的竞争性，并且潜力的显着假想部分解释了两个系统中的弹性散射横截面和阈值异常。
We use a phenomenological nucleus-nucleus optical potential constructed in the light of a potential developed by Ginocchio to study the elastic angular distributions of different nuclear systems near Coulomb barrier. The differential cross section ratios of elastic to Rutherford are studied for systems $^{14}$N+$^{56}$Fe and $^{14}$N+$^{90}$Zr for several colliding energies. Our theoretical predictions are well competitive with the experimental data, and the significantly small imaginary part of the potential explains the elastic scattering cross section and threshold anomaly in both systems.
