Phys. Rev. C 62, 034319 (2000) [17 pages]Structure of light S=-2 nuclei and hyperon mixingReceived 25 January 2000; published 23 August 2000 The one-boson-exchange-model (OBEM) and quark-cluster-model (QCM) interactions are applied to the structure study of the ground states in light S=-2 nuclei with the [core+Λ+Λ]+[core+Ξ+N] model and the core+(3q)+(3q) cluster model, respectively. The core+(3q)+(3q) cluster model proposed here is a model designed to use the QCM interactions in finite nuclear systems. We found that the OBEM interactions predict a double-Λ hypernuclear state for the ground state of light S=-2 nuclei, while the QCM interaction with a bound H dibaryon predicts a bound H-nuclear state, although the structure of the H state in nucleus is considerably different from the free one. © 2000 The American Physical Society URL:
