Abstract
The four-body equations of Alt, Grassberger and Sandhas are solved for a system of four nucleons, using realistic NN interactions in channels 1S0, 3S1−3D1, 1P1, 3P0, 3P1 and 3P2. The results of the calculation are compared with data for the reactions dd → dd, dd → p 3H and n3H → n 3H. The calculations indicate that the nucleon-nucleon p-waves have a strong effect on 4N observables, but one finds some disagreement with data that indicates the need for a 3N force or new 2N+3N force models.
