Differential cross sections for have been measured with tagged real photons for incident photon energies from 0.75 to 1.95 GeV. Mesons were identified by missing mass reconstruction using kinematical information for protons scattered in the production process. The data provide the first extensive angular distribution measurements for the process above . Comparison with preliminary results from a constituent quark model support the suggestion that a third resonance with mass couples to the channel.
