| Summary: | Elastic and breakup cross sections in nucleon-deuteron scattering at intermediate energies are calculated using a realistic two-nucleon potential and three-nucleon potentials based on the exchange of two pions among three nucleons.
Attractive effects of the pion-exchange at medium range region in the three-nucleon potential are recovered by using a shorter range cutoff.
It is shown that these effects increase the cross sections at backward angles, which tends to reduce discrepancies between theoretical calculations and experimental data. |
