Evidence of three-body force effects in neutron-deuteron scattering at 95 MeV

Recently, we have reported a measurement of the neutron-deuteron elastic scattering differential cross section at 95 MeV. In the present work, the previous results are confirmed with an independent measurement performed with another setup. The new data cover the full angular distribution by combinin...

Description
Summary:Recently, we have reported a measurement of the neutron-deuteron elastic scattering differential cross section at 95 MeV. In the present work, the previous results are confirmed with an independent measurement performed with another setup. The new data cover the full angular distribution by combining neutron detection and deuteron detection, and have an unprecedented precision in the region of the cross-section minimum, where three-nucleon forces are expected to be significant. The effect already identified in the previous measurement is clearly seen in the present data, which agree well with theoretical descriptions including three-nucleon forces.
