Phys. Rev. Lett. 81, 1183–1186 (1998)Cross Section Minima in Elastic Nd Scattering: Possible Evidence for Three-Nucleon Force EffectsReceived 14 January 1998; published in the issue dated 10 August 1998 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 60 MeV. Adding the three-nucleon forces fills up those minima and reduces the discrepancies significantly. © 1998 The American Physical Society URL:
