title = "Cross section for γn→π0n measured at the Mainz A2 experiment",
abstract = "The γn→π0n differential cross section evaluated for 27 energy bins span the photon-energy range 290-813 MeV (W=1.195-1.553 GeV) and the pion c.m. polar production angles, ranging from 18 to 162, making use of model-dependent nuclear corrections to extract π0 production data on the neutron from measurements on the deuteron target. Additionally, the total photoabsorption cross section was measured. The tagged photon beam produced by the 883 MeV electron beam of the Mainz Microtron MAMI was used for the π0-meson production. Our accumulation of 3.6×106 γn→π0n events allowed a detailed study of the reaction dynamics. Our data are in reasonable agreement with previous A2 measurements and extend them to lower energies. The data are compared with predictions of previous said, maid, and BnGa partial-wave analyses and to the latest said fit MA19 that included our data. Selected photon-decay amplitudes N∗→γn at the resonance poles are determined for the first time.",
