摘要：
Breakup in nucleon-deuteron scattering is described. The description is based on a coupled-channel two-baryon potential that allows for the virtual excitation of a nucleon to a Delta isobar. The Coulomb interaction is not included. Channel coupling gives rise to an effective three-nucleon force. The three-particle scattering equations are solved by real-axis integration using a separable expansion of the two-baryon transition matrix. Examples for spin-averaged and spin-dependent observables are calculated and compared with experimental data.
