npelastic scattering analyzing power characteristics at intermediate energies

This is the authors' abstract. We don't add key points for this paper.

Recent measurements of charge symmetry breaking in the np system at 477 MeV, and of A₀₀ₙₙ for np elastic scattering at 220, 325, and 425 MeV also yield accurate analyzing power data. These data allow the energy dependence of the analyzing power zero-crossing angle and the slope of the analyzing power at the zero-crossing angle to be determined. The incident neutron energies span a region where the zero-crossing angle is strongly energy dependent (Eₙ250 MeV) to where it is almost independent of energy (Eₙ>350 MeV). The results are compared to current phase-shift analysis predictions, recently published data, and the predictions of the Bonn and Paris potentials.
