Abstract

The previous Glasgow single-pion energy-dependent photoproduction analysis from protons and neutrons has been extended to include more recent experimental data. This analysis uses fixes- t dispersion relations with a resonance parametrization at low centre of mass energies and a Regge parametrization at high energies. An energy-dependent analysis has also been performed beneath 1.75 GeV for proton targets. Resonance mass, width and couplings are presented for 26 resonances.
