The cross section minima in elastic Nd scattering: a ``smoking gun'' for three nucleon force effects
arXiv:nucl-th/9801018 · doi:10.1103/PhysRevLett.81.1183
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 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.
