Detailed structure calculations in Ξ12Be, Xi7H and Ξ10Li are performed within the framework of the microscopic of four-body cluster models. 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. Ξ7H andΞ10≤ are predicted to have bound states. We propose to observe the bound states in future (K-,K+) experiments using 7Li and 10B targets in addition to the standard 12C target. The experimental confirmation of these states will provide information on the spin- and isospin-averaged ΞN interaction.
