Abstract
Neutron-deuteron elastic scattering cross sections are calculated at d ifferent energies using modern nucleon-nucleon (NN) interactions and t he Tucson-Melbourne three-nucleon force adjusted to the triton binding energy. Predictions based on NN forces only underestimate nucleon-deu teron data in the minima at higher energies starting around 60 MeV. Ad ding the three-nucleon forces fills up those minima and reduces the di screpancies significantly. [S0031-9007(98)06806-9].
