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