Neutron-proton analyzing power at 12 MeV and inconsistencies in parametrizations of nucleon-nucleon data


Journal Article

We present the most accurate and complete data set for the analyzing power Ay (θ) in neutron-proton scattering. The experimental data were corrected for the effects of multiple scattering, both in the center detector and in the neutron detectors. The final data at En = 12.0 MeV deviate considerably from the predictions of nucleon-nucleon phase-shift analyses and potential models. The impact of the new data on the value of the charged pion-nucleon coupling constant is discussed in a model study. © 2008 Elsevier B.V. All rights reserved.
