Explicit pionic degrees of freedom in deuteron photodisintegration in the Delta-resonance region

Abstract

Photodisintegration of the deuteron above pi-threshold is studied in a coupled channel approach including N-Delta- and pi-d-channels with pion retardation in potentials and exchange currents.
