The $\gamma n \to \pi^0 n$ differential cross section evaluated for 27 energybins span the photon-energy range 290-813 MeV (W = 1.195-1.553 GeV) and thepion c.m. polar production angles, ranging from 18 deg to 162 deg, making useof model-dependent nuclear corrections to extract pi0 production data on theneutron from measurements on the deuteron target. Additionally, the totalphotoabsorption cross section was measured. The tagged photon beam produced bythe 883-MeV electron beam of the Mainz Microtron MAMI was used for the 0-mesonproduction. Our accumulation of 3.6 x 10^6 $\gamma n \to \pi^0 n$ eventsallowed a detailed study of the reaction dynamics. Our data are in reasonableagreement with previous A2 measurements and extend them to lower energies. Thedata are compared to predictions of previous SAID, MAID, and BnGa partial-waveanalyses and to the latest SAID fit MA19 that included our data. Selectedphoton decay amplitudes $N^* \to \gamma n$ at the resonance poles aredetermined for the first time.
