Discrepancies between global nucleon-nucleon phase shifts and new data for n-p scattering at 16.9 MeV


Journal Article

Data for the analyzing power Ay(θ) for n-p scattering at 16.9 MeV have been measured for the range from 50 to 145>°(c.m.). Eleven values are reported to an accuracy of about ±0.002, the highest overall precision ever obtained in any fast-neutron polarization experiment. Predictions based on phase-shift sets obtained from global analyses of nucleon-nucleon scattering disagree significantly with the new data. The data are sufficiently precise to show a dependence on the f-wave spin-orbit phase parameter. © 1977 The American Physical Society.
