21. Conclusions 1.Ten resonances in the different strangeness and isospin channels. Degenerate in J P =1/2 -, 3/2 -, 5/2 -. 2.Radiative widths are of the order of 1MeV. 3.Radiative decay widths are different about one order of magnitude between the widths for different charge states of the same resonance.
