用反对称超核分子动力学(HyperAMD)方法研究了10ΛBe和12ΛBe的低能级结构.发现在10ΛBe中,9 Be的第一激发态1/2+上移了约700 keV。在12ΛBe中,通过加入Λ超子,11 Be的宇称反转基态被恢复。在本文中,我们讨论了这些结构变化的原因和变形的10ΛBe和12Λ Be。
The low-lying level structure of 10ΛBe and 12ΛBe was studied with the antisymmetrized molecular dynamics for hypernuclei (HyperAMD). It is found that the first excited state 1/2+ of 9Be is shifted up by about 700 keV in 10ΛBe. In 12ΛBe, the parity-inverted ground state of 11Be is reverted by adding the Λ hyperon. In this article, we discuss the reason for these structure changes and the deformation of 10ΛBe and 12Λ Be.
