Abstract
Neutron-deuteron elastic scattering cross sections are calculated at different energies using modern nucleon-nucleon ( ) interactions and the Tucson-Melbourne three-nucleon force adjusted to the triton binding energy. Predictions based on forces only underestimate nucleon-deuteron data in the minima at higher energies starting around 60 MeV. Adding the three-nucleon forces fills up those minima and reduces the discrepancies significantly.
