【 摘 要 】

The low-lying level structure ofΛ10Be andΛ12Be was studied with the antisymmetrized molecular dynamics for hypernuclei (HyperAMD). It is found that the first excited state 1/2+of9Be is shifted up by about 700 keV inΛ10Be. InΛ12Be, the parity-inverted ground state of11Be is reverted by adding the Λ hyperon. In this article, we discuss the reason for these structure changes and the deformation ofΛ10Be andΛ12Be.
