Abstract

Deformed multi-Λ hypernuclei are studied within a relativistic mean-field model. In this paper, I take some N=Z "hyper-isotope" chains, i.e., BenΛ8+n,NenΛ20+n, and SinΛ28+n systems where n=2,4 for Be and n=2,8 for Ne and Si. A sign of two-He2Λ6 cluster structure is observed in the two-body correlation in Be4Λ12. In the Ne hyper-isotopes, the deformation is slightly reduced by addition of Λ hyperons, whereas it is significantly reduced or even disappears in the Si hyper-isotopes.
