Low-energy NN tensor force from n -p scattering: Results of an accurate experimental approach


Journal Article

The spin-dependent neutron-proton total cross-section differences ΔσL and ΔσT have been measured between En=5 and 20 MeV in longitudinal and transverse nucleon spin orientations. From these data the 3S1-3D1 mixing parameter ε1, which characterizes the nucleon-nucleon tensor force at low and intermediate energies, was determined in a model-insensitive way. In combination with measurements at higher energies, our values for ε1 support a nucleon-nucleon tensor interaction that is stronger than predicted by all modern high-precision nucleon-nucleon potential models and phase-shift analyses.
