Detailed structure calculations in Ξ-12Be, Ξ-5H, Ξ-9Li, Ξ-7H, and Ξ-10Li are performed within the framework of the microscopic two-, three-, and four-body cluster models using the Gaussian expansion method. We adopted effective ΞN interactions derived from the Nijmegen interaction models, which give rise to substantially attractive Ξ-nucleus potentials in accordance with the experimental indications. Ξ-7H and Ξ-10Li are predicted to have bound states. we propose to observe the bound states in future (K-,K+) experiments using Li7 and B10 targets in addition to the standard C12 target. The experimental confirmation of these states will provide information on the spin- and isospin-averaged ΞN interaction.
