Differential cross sections for [Formula presented] 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 [Formula presented]. Comparison with preliminary results from a constituent quark model support the suggestion that a third [Formula presented] resonance with mass [Formula presented] couples to the [Formula presented] channel.
