Abstract

An extended version of the antisymmetrized molecular dynamics to study structure of pp-sdsd shell hypernuclei is developed. By using an effective ΛN\Lambda N interaction, we investigate energy curves of Λ9^9_\LambdaBe, Λ13^{13}_\LambdaC and Λ20,21^{20,21}_\LambdaNe as function of nuclear quadrupole deformation. Change of nuclear deformation caused by Λ\Lambda particle is discussed. It is found that the Λ\Lambda in p-wave enhances nuclear deformation, while that in s-wave reduces it. This effect is most prominent in Λ13^{13}_\LambdaC. The possibility of the parity inversion in Λ20^{20}_\LambdaNe is also examined.
