Three-Nucleon Force Effects in the FSI configuration of the d(n, nn)p Breakup Reaction

TL;DR

This paper investigates the effects of three-nucleon forces in the final state interaction configuration of the deuteron breakup reaction at 200 MeV, revealing effects across various scattering angles.

Contribution

It provides new insights into three-nucleon force effects in the FSI configuration of the d(n, nn)p reaction at intermediate energies.

Findings

3N force effects are present at forward angles in the FSI breakup cross section.

Effects are consistent with those observed in elastic nucleon-deuteron scattering.

The study extends understanding of 3N forces beyond intermediate and backward angles.

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.
