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.

I do not see any.
The manuscript present recent results on nucleon-deuteron scattering with modern interactions, including 3-body forces. The author shows that 3-body effects increase the cross sections at backward angles, which improves the agreement between theory and experiment.
The text is clearly written and concise.
A minor typography problem: in eq.(1) I do not understand the symbol in front of tau_3 and of sigma_3.
After the authors have adapted the text accordingly, I recommend the publication of the manuscript.
