Application of the Faddeev Equations to the Three-Nucleon Problem

The low-energy three-nucleon system is considered using the multiple-scattering formalism of Faddeev and an approximation scheme that preserves bound-state and three-particle scattering unitarity. The approximations involve the use of nonlocal separable potentials to describe the low-energy nucleon-nucleon interaction and a phenomenological three-body force to represent the effects on the three-nucleon system of the nucleon-nucleon tensor and short-range interactions. The neutron-deuteron scattering problem above and below the three-particle threshold, and the triton binding-energy problem, are solved exactly. The theoretical results are in impressive agreement with the experimental data.
