Abstract

The deformation change of \({^{9}_\Lambda}\) Be and the low-lying states of \({^{12}_{\Lambda}}\) Be are studied by using the antisymmetrized molecular dynamics for hypernuclei (HyperAMD). In \({^{9}_{\Lambda}}\) Be, the Λ hyperon in p orbit enhances nuclear quadrupole deformation, while the Λ hyperon in s orbit reduces it. In \({^{12}_{\Lambda}}\) Be, the ground state parity inverted in 11Be is reverted in \({^{12}_{\Lambda}}\) Be by adding a Λ hyperon as an impurity (impurity effect).
