Abstract

Photo disintegration of the deuteron and photo pionproduction on the deuteron are described in the region of the Δ-resonance. The two reactions are unitarily coupled. A novel definition of electromagnetic exchange currents in the presence of pionproduction is given. Numerical predictions are done for spin-independent and spin-dependent observables of both reactions. The sensitivity of the results with respect to the nucleon-Δ transition current and with respect to the irreducible nucleon-Δ potential is studied.
