Nuclear Symmetry Energy Extracted from the (p,n) Reaction Experimental Data

  • 摘要: 通过分析(p,n)电荷交换反应的微分散射截面数据,得到了核子光学势实部的同位旋矢量项。(p,n)反应的微分散射截面的大小正比于核子光学势实部的同位旋矢量项v1的平方,利用平面波玻恩近似可以直接提取v1的值。再根据HVH理论,利用v1的值能够得到对称能Esym(ρ0)和它的密度依赖斜率L(ρ0)的值。得到的结果Esym(ρ0)=28.5 MeV, L(ρ0)=76.0 MeV与分析原子核质量和其他核实验数据得到的结果符合较好。

    The isovector term of the real part of the nucleon optical potential is obtained by analysing differential cross section data of (p,n) charge exchange reaction. The magnitude of the differential cross section of (p,n) experiment is proportional to the square of the isovector term of the real part of the nucleon optical potential v1, so the extraction of the value of v1 is straightforward by using the plane wave Born approximation. Based on the Hugenholtz-Van Hove theorem, the nuclear symmetry energy Esym(ρ0) and its density slope L(ρ0) are estimated by using the extracted value of v1. The calculated results Esym(ρ0)=(28.5±2.0) MeV, L(ρ0)=(67.0±5.0) MeV agree reasonably with those extracted by analysing nuclear masses and other experimental data.
