Neutron-proton scattering. I. Differential cross section at 63.1 MeV

Abstract
The neutron-proton differential cross section has been measured at 63.1 MeV. The data span an angular range from θc.m.=40° to 165° with a relative precision of ≳ 3.0%. A different angular behavior is observed in the present results as compared to that in the data between 55 and 65 MeV currently used in phase parameter analyses.
