摘要
通过同时符合3He引起的核反应截面和弹性散射角分布实验数据,获得了一套适用于靶核质量数为20≤A≤209,3He入射能量从阈能到250 MeV的普适唯象光学势。对3He普适唯象光学势进行物理分析,计算和分析了3He普适唯象光学势实部和虚部的径向关系。结果表明,这套3He普适唯象光学势在物理上是合理的。
A new set of global phenomenological optical potential parameters for helium-3 has been obtained,by simultaneously fitting the experimental data of reaction cross sections and elastic scattering angular distributions in the mass range of target nuclei 20≤A≤209 with incident helium-3 energies below 250 MeV.The global optical potential is physically analyzed.The radial dependence of the global phenomenological optical potential are calculated and analyzed.These results show that the helium-3 global phenomenological optical potential is reasonable physically.
