摘　　要：利用手征SU(3)夸克模型,采用共振群方法得到Ξ-N作用相互非定域位以及Ξ超子与10ΞHe壳心核的相互作用势,并利用其计算Ξ4He、Ξ8He1、Ξ11B的基态结合能.计算结果表明利用手征SU(3)夸克模型能得到与实验相近的结果.同时本文也对Ξ超核结合能的性质做了初步研究,以进一步加深对重子-重子相互作用的了解.Using the resonating group method,the non-local ΞN interaction and Ξ-core of Ξ^10He interaction based on the chiral SU（3） quark model are obtained,and the bound energies BΞ of hypernuclei Ξ^4He,Ξ^8He and Ξ^11B are calculated.It is shown that the calculated results bascially agree with the date of experiment.In the same time, the writer makes primarily investigation to Ξ hypernuclei which is to strengthen understand for the bayon-bayon interaction in the article.
