Abstract
The coupled-channel method developed previously is applied to the system of resonances above the threshold for Zweig-allowed decays (). The structure of is calculated for representative values of . Typically the resonance has a complex structure with a total width 10-40 MeV and . This structure has a strong dependence which may allow the determination of from the observed structure of in the region. The contribution of each exclusive channel is shown. Higher resonances are briefly discussed.
