基于Skyrme力的微观光学模型及Modified Skyrme Like模型,以n+208 Pb反应为例研究了核物质的宏观参量对核反应数据的影响.研究结果表明:饱和密度处对称能的值Esym(ρ0)、核子同位旋标量有效质量m*s,0及不可压缩系数K0的变化对核反应数据的影响较大.通过分析计算给出近似取值:Esym(ρ0)≈31.45MeV,m*s,0≈0.66 m,(m为自由核子质量),L≈69.96 MeV.
Based on Microscopic Optical Model of Skyrme force and Modified Skyrme Like Model, choos- ing the reaction of n+208Pb as example, the effect of Nuclear Matter Macroscopic Parameters on the nuclear reaction data is studied. The results indicate that the nuclear reaction data is very sensitive to the value of symme- try energy at normal density Esym(po), the nucleon iso-scalar effective mass m*s,0 and the incompressibility coefficient K0. Through the analyse of calculations, the approximate values are obtained, i.e.Esym(ρ0)≈31.45MeV,m*s,0≈0.66 m (where m is the mass of nucleon in free-space), L≈69.96 MeV.
