Widths of Xi Hypernuclear States

The $\Lambda$ and neutron decay widths of $\Xi$ hypernuclear states, based on calculated $\Xi N \to \lala$ mixing amplitudes, are estimated. The widths which result from using the Nijmegen Model D interaction are sufficiently small, of order 1.5 MeV, that experiments to observe $\Xi$ hypernuclear states using the $(K^-,K^+)$ reaction may be feasible.
