New measurements of 2^{2}H(γ⃗\vec \gamma,p)n and spin problems in coupled NΔ\Delta/NN interactions

New precision measurements of the 2H(γ→,p)n reaction taken with tagged polarized photons, and covering a wide angular range, are presented for incident energies between 113 and 315 MeV. In the region of the Δ resonance, the photodisintegration observables can potentially be used to probe the NΔ interaction. Coupled-channel calculations are in agreement with cross sections measured with linear polarization parallel to the reaction plane but fail to account for data taken with perpendicular kinematics
