我们从2 0 8Pb2 0 8Pb等向量巨偶极子共振的质心能E−1及其电极化率αD出发,对Skyrme-Hartree-Fock模型中的等向量核相互作用作了严格的约束.用贝叶斯分析方法发现,E−1和αD主要由ρ⋆=0.0 5fM−3时的核对称能E S ym和饱和密度下的向量核子有效质量m v⋆决定.在90%的置信度下,E S ym(ρ⋆)=16.4−0.9+1.0 MeV,mv⋆/m=0.79−0.0 6+0.0 6。
We put a stringent constraint on the isovector nuclear interactions in the Skyrme-Hartree-Fock model from the centroid energy E− 1 of the isovector giant dipole resonance in 208 Pb as well as its electric polarizability α D. Using the Bayesian analysis method, E− 1 and α D are found to be mostly determined by the nuclear symmetry energy E s y m at about ρ⋆= 0.05 fm− 3 and the isovector nucleon effective mass m v⋆ at the saturation density. At 90% confidence level, we obtain E s y m (ρ⋆)= 16.4− 0.9+ 1.0 MeV and m v⋆/m= 0.79− 0.06+ 0.06.
