The interaction between a nucleon and a [Delta] isobar is studied. The nucleon-[Delta] potential is derived from a nonrelativistic quark model. It is compared with a corresponding one based on meson exchange. The quark-model potential is strongly repulsive at small relative distances. The effects of the potential on elastic and inelastic nucleon-nucleon and pion-deuteron scattering are calculated. Some observables show sensitivity with respect to the chosen nucleon-[Delta] potential.
