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