Widths of $Ξ$ Hypernuclear States

Abstract

The $Λ$ and neutron decay widths of $Ξ$ hypernuclear states, based on calculated $ΞN \to \lala$ 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 $Ξ$ hypernuclear states using the $(K^-,K^+)$ reaction may be feasible.
