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40Ca及相应超核的超形变态进行了研究,计算结果表明,基态的A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.
The superdeformed (SD) states in medium heavy hypernuclei with core nuclei of Ar isotopes and 40Ca are studied in the frame of Skyrme Hartree-Fock (SHF)+ BCS model together with a microscopic AN interaction.The calculation indicates that the A separation energy SA of ground state is larger than that of SD state.The result is consistent with the antisymmetrized molecular dynamics (AMD) calculation,but inconsistent with that of relativistic mean field (RMF).The difference comes from the different interaction and density distribution in the core nuclei and the corresponding hypernuclei.
