Abstract
Differential cross sections for photoproduction from protons have been measured at in the backward direction. A bump structure has been observed above GeV in the total energy. No such bump is observed in , and photoproductions. It is inferred that this unique structure in photoproduction is due to a baryon resonance with a large component that is strongly coupled to the channel.
