Kaonic nuclei excited by the (K-, N) reaction

We show that kaonic nuclei can be produced by the ( ${K}^{\ensuremath{-}},p$) and ( ${K}^{\ensuremath{-}},n$) reactions. The reactions are shown to have cross sections experimentally measurable. The observation of kaonic nuclei gives a kaon-nucleus potential which answers the question as to the existence of kaon condensation in dense nuclear matter, especially in neutron stars.
