Abstract
Many excited baryon states which are predicted to exist in models of the nucleon which treat three constituent quarks symmetrically are not present in analyses of pion-nucleon elastic scattering. The properties and quantum numbers of the nonstrange baryons accessible at new electron and photon facilities are described in a model of the baryon spectrum and strong decays based one-gluon exchange. A model which is able to describe almost all of the channels open for strong decays of the established and missing states is outlined. This model gives a reasonable description of the strong couplings of known states, and is used to determine the best decay channels for discovering missing baryon states.
