Conclusions
1. Ten resonances in the different strangeness and isospin channels. Degenerate in JP=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.
