Photoproduction ofπ0from Hydrogen near the Second Pion-Nucleon Resonance

Abstract

Angular distributions for ${\pi }^0$ 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 $d_{\frac{3}{2}}$ state is seen in the resonance region. A possible high-momentum-transfer enhancement of the cross section is discussed.
