Abstract
We investigated three-nucleon (3N) force effects in the final state interaction (FSI) configuration of the d(n, nn)p breakup reaction at the incoming nucleon energy E n = 200 MeV. Although 3N force effects for the elastic nucleon-deuteron scattering cross section at comparable energies are located predominantly in the region of intermediate and backward angles, the corresponding 3N force effects for the integrated FSI configuration breakup cross section are found also at forward scattering angles.

Report
The manuscript reports the theoretical study of three-nucleon force (3NF)
effects on neutron-deuteron breakup reaction in the so-called final state
interaction (FSI) kinematics. This is an interesting configuration where
two neutrons have very low relative momentum and move away from the
remaining proton, as the process is very sensitive to the neutron-neutron
scattering length, over which still remains a controversy regarding its
experimental value.
The study shows, for incoming neutron energy E_n = 200 MeV, significant
3NF effects not only at intermediate and backward angles, as in the
elastic scattering case, but also at forward angles. The manuscript is
well-written, shows interesting and relevant results, and the authors are
world experts in this topic.
Therefore I consider the manuscript in well-suited form to be published
at the SciPost Physics Proceedings.
