Abstract
The present status of the theoretical description of electromagnetic reactions on the deuteron above pion threshold is reviewed. Three major topics are considered: (i) retardation effects in π-meson exchange contributions to NN-interaction and meson exchange currents in deuteron photodisintegration above π-threshold in the Δ-resonance region, (ii) off-shell effects in the one-body current treated in a simple pion cloud model in, deuteron photodisintegration in and above the Δ-resonance region, and (iii) final state interaction effects in photoproduction of π and η mesons on the deuteron.Keywords
