Single π⁰ Photoproduction off the Deuteron

The γn→π⁰n cross section (W = 1195 - 1533 MeV) [1] and beam asymmetry (W = 1271 - 1424 MeV) [2] has been measured for the first time. The data were collected in the A2 Hall of the MAMI tagged photon beam facility with the Crystal Ball and TAPS calorimeters covering pion CM angles 18 -162 degrees and from 49 to 148 degrees.  The extracted values of cross sections and asymmetries have been compared to predictions based on PWAs of the existing pion-photoproduction database. We include the SAID, MAID, and Bonn-Gatchina analyses; while a revised SAID fit, including the new A2 measurements, has also been performed. Selected photon-decay amplitudes N*→γn at the resonance poles are determined for the first time.
