摘要：
We have used realistic local interactions based on the recent update of the strangeness -2 Nijmegen ESC08c potential to calculate the bound-state problem of the Xi NN system in the (I)J(P) = (1/2)3/2(+) state. We found that this system presents a deeply bound state lying 13.5 MeV below the Xi d threshold. Since in the lowest order, pure S-wave configuration, this system cannot decay into the open Lambda Lambda N channel, its decay width is expected to be very small. We have also recalculated the (I)J(P) = (3/2)1/2(+) state and we have compared our results with those of quark-model-based potentials.
