and so do Kaon-eta, Kaon-eta', .... For such a system one obtains only 1 eigenphase in RSE. When, moreover, the inelasticities are weak, Kaon-pion, Kaon-eta and Kaon-eta' have the same phase. Consequently, the phases measured for Kaon-pion also represent the experimental phases for Kaon-eta and Kaon-eta'. |
