S = −2 Nuclear Phenomena and ΞN Interaction
The ΞN G-matrix interaction is derived from the Nijmegen OBE model, and applied to the calculations of Ξ −-nucleus bound states with use of the DDHF formalism. The obtained Ξ − binding energies in 12C are consistent with the values indicated by the events of simultaneous emissions of two Λ hypernuclei observed in the KEK-E176 experiment. In spite of shallow binding of Ξ − in light nuclei, our Ξ-nucleus potentials are shown to become deep with increase of mass number owing to the strong attraction in ΞN odd states.
