Abstract

The sensitivity of neutron-proton elastic scattering observables to variations in the low angular momentum T=0 phase shifts is studied at $E_{lab = 325}$ MeV. It is found that the J=1 coupling parameter $ε_{1}$ is not well determined by existing data. This uncertainty in $ε_{1}$ permits models with quite different tensor forces to describe the extant data. Implications and possible experimental resolution of such ambiguities are discussed.
