Abstract: The relativistic Faddeev equation for three-nucleon scattering is formulatedin momentum space and directly solved in terms of momentum vectors withoutemploying a partial wave decomposition. Relativistic invariance is achieved byconstructing a dynamical unitary representation of the Poincar\-e group on thethree-nucleon Hilbert space. The exclusive breakup reaction at 508 MeV iscalculated based on a Malfliet-Tjon type of two-body interaction and the crosssections are compared to measured cross sections at this energy. We find thatthe magnitude of the relativistic effects can be quite large and depends on theconfigurations considered. In spite of the simple nature of the modelinteraction, the experimental cross sections are in surprisingly good agreementwith the predictions of the relativistic calculations. We also find thatalthough for specific configurations the multiple scattering series convergesrapidly, this is in general not the case.
