The N(1520) 3/2- helicity amplitudes from an energy-independent multipole analysis based on new polarization data on photoproduction of neutral pions

J. Hartmann, H. Dutz, A. V. Anisovich +74

New data on the polarization observables T, P, and H for the reaction $γ p \to p π^{0}$ are reported. The results are extracted from azimuthal asymmetries when a transversely polarized…

Photoproduction of pi0-mesons off neutrons in the nucleon resonance region

M. Dieterle, I. Keshelashvili, J. Ahrens +71

Precise angular distributions have been measured for the first time for the photoproduction of $π^{0}$ -mesons off neutrons bound in the deuteron. The effects from nuclear Fermi mot…

Measurement of the beam-helicity asymmetry $I^{⊙}$ in the photoproduction of $π^{0} π^{\pm}$ -pairs off protons and off neutrons

M. Oberle, J. Ahrens, J. R. M. Annand +72

Beam-helicity asymmetries have been measured at the MAMI accelerator in Mainz for the photoproduction of mixed-charge pion pairs in the reactions $γ p \to n π^{0} π^{+}$ …
