Angular distributions for π0 photoproduction from hydrogen at energies between 660 and 800 MeV and proton center-of-mass angles from 0° to 140° have been measured and analyzed. Some variation from a pure d3/2 state is seen in the resonance region. A possible high-momentum-transfer enhancement of the cross section is discussed.
