Medium-heavy Superdeformed Hypernuclei in Skyme Hartree-Fock Model

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 ΛN interaction. The calculation indicates that the Λ separation energy S_Λ 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.
