Neutron-deuteron elastic scattering cross sections are calculated at different energies using modern nucleon-nucleon (NN ) interactions and the Tucson-Melbourne three-nucleon force adjusted to the triton binding energy. Predictions based on NN forces only underestimate nucleon-deuteron data in the minima at higher energies starting around 60thinspMeV. Adding the three-nucleon forces fills up those minima and reduces the discrepancies significantly. {copyright} {ital 1998} {ital The American Physical Society}
