摘    要:核子-核子碰撞截面(σNN)是描述原子核反应模型中的重要物理量。 核子-核子碰撞截面包括质子-质子碰撞截面(σpp)、中子-中子碰撞截面(σNN)和中子 质子碰撞截面(σnp), 它们随着核子能量与核物质密度的改变而变化。人们在目前研究中提出了多种核子-核子碰撞截面关于能量和核物质密度的参数化公式,通过计算12C+12C的完全反应截面,比较了不同入射能量下使用各种核子-核子碰撞截面参数化公式对12C完全反应截面的影响。 The nucleus-nucleus cross sections(σNN) include the proton-proton cross section, neutron-neutron cross section, and neutron-proton cross section. σNN change with the variations of the incident energies and the densities. Some parameterizations of σNNas a function of incident energy and density have been proposed in the theoretical and experimental study of nuclear reactions. Through the calculation of reaction cross sections of 12C+12C at different energies, the effect of different σNN parameterizations in the reaction cross sections of 12 are studied. 

Abstract:The nucleus-nucleus cross sections(σNN) include the proton proton cross section,neutron-neutron cross section, and neutron-proton cross section. σNNchange with the variations of the incident energies and the densities. Some parameterizations of σNN as a function of incident energy and density have been proposed in the theoretical and experimental study of nuclear reactions. Through the calculation of reaction cross sections of 12C+12C at different energies, the effect of different σNN parameterizations in the reaction cross sections of 12 are studied.
