Aspects of exclusive nucleon diffraction dissociation

Some aspects of inelastic nucleon diffraction into Nπ in the context of a double peripheral (Deck) description are discussed. From new experimental data at the highest energies available one observes that in addition to the π exchange mechanism there are other contributions and corrections to be included in the production amplitude: nucleon exchange, direct nucleon graph, and various final state interactions. Especially the latter are investigated in an attempt to explain the momentum transfer distribution as considered in different mass and decay angular intervals. The fundamental dynamical role of the peripheral structure of inelastic diffraction in impact parameter space is pointed out. (Auth.)
