IMPURITY EFFECTS IN $_\Lambda^{12}{\rm{Be}}$ AND $_\Lambda^{21}{\rm{Ne}}$ HYPERNUCLEI

Abstract

The structures of the ground and low-lying states of [Formula: see text] and [Formula: see text] hypernuclei are studied with AMD. By a Λ hyperon, the parity reversion of the [Formula: see text] ground state and binding of the unbound α + 16 O cluster state in [Formula: see text] are found. Furthermore, intra-band B(E2) reduction in the [Formula: see text] band of [Formula: see text] is larger than that in the [Formula: see text] band, because of the reduction of the inter-cluster distance between α and 16 O cluster of the [Formula: see text] band.
