采用Skyrme Hartree-Fock模型和微观的核子-超子相互作用对Ar同位素和~(40)Ca及相应超核的超形变态进行了研究,计算结果表明,基态的Λ超子分离能比激发态的大。这一结果与反对称化分子动力学模型的结果一致,而与相对论平均场的结果相反。这区别主要来源于不同模型中不同的相互作用导致的核心核及相应超核密度分布的不同。
Using the Skyrme Hartree-Fock model and the microscopic nuclear-hyperon interaction, the super-deformation of Ar isotopes and ~ (40) Ca and the corresponding hypernuclei were studied. The results show that the Λ hyperon separation of the ground state can be better than that of the excited state Big This result is consistent with the results of the antisymmetric molecular dynamics model, as opposed to the relativistic mean field. The difference mainly comes from the difference in density distribution of core nuclei and corresponding super-nuclei caused by different interactions in different models.
