Abstract
The reaction has been measured with the TAPS calorimeter at the Mainz Microtron accelerator facility MAMI for energies between . The cross section’s differential in angle and energy have been determined for the photon in three bins of the excitation energy. This reaction channel provides access to the magnetic dipole moment of the resonance and, for the first time, a value of has been extracted.
