Charged-pion photoproduction measurement on deuterium in the Δ(1236) region using a quasi-monochromatic photon beam - Faure, J.-L.; Argan, P.; Audit, G.; Bloch, A.; De Botton, N.; Ghedira, L.; Laget, J.-M.; Magnon, A.; Schuhl, C.; Mazzucato, E.; Vincent, E.; Tamas, G.; et al. (Elsevier)
Charged-pion photoproduction spectra on hydrogen and deuterium have been measured using an in-flight positron annihilation photon beam. Pions were detected in magnetic spectrometers. The experiment consisted of π^+/- angular distributions at 300 MeV, and fixed-angle excitation curves at 20^o (π^+/-) and 55^o (π^+/-) in the photon energy range 300-460 MeV. Experimental data are compared to a calculation by Laget which includes final-state nucleon-nucleon interaction and Pauli correlations. The overall agreement is satisfactory; however, the model slightly overestimates the nucleon-nucleon rescattering contribution.
