Abstract
The reactions and have been measured from their thresholds up to the center-of-mass energy GeV with the tagged-photon facilities at the Mainz Microtron, MAMI. Differential cross sections were obtained with unprecedented accuracy, providing fine energy binning and full production-angle coverage. A strong cusp is observed in the total cross section and excitation functions for photoproduction at the energies in vicinity of the threshold, MeV (MeV). This behavior is explained in a revised MAID isobar model by a significant branching of the nucleon resonance to both, and , confirming the existence and constraining the properties of this poorly known state.
