Abstract The reliability of the resonating group method is studied above the three-body breakup threshold. In particular, the real part of the elastic n-d phase shift is calculated in a model of three spinless bosons interacting by a separable Yamaguchi potential for which exact Faddeev results are available. Spurious singularities which are caused by the distortion part of the resonating group ansatz are eliminated by a least squares method.

The four-nucleon bound state and scattering below three-body breakup threshold are described. The description is based on a realistic coupled-channel potential which allows the excitation of a single nucleon to a Δ isobar. In the four-nucleon system the Δ isobar mediates effective two-, three- and four-nucleon forces. The effect of the four-nucleon force is found to be much smaller than the effect of the three-nucleon force.

A modified version of the Faddeev three-body equation to accommodate the long-range Coulomb interaction is applied to the proton-deuteron scattering problem at energies above the three-body breakup threshold. Numerical results for elastic and breakup cross sections in proton-deuteron scattering with effects of three-nucleon forces are compared with experimental data.
