Abstract

Deuteron photodisintegration is calculated in the photon energy range \(500{-}600\) MeV, adopting a standard theory in which the nucleonic one-body current, meson exchange currents and isobar excitations are taken into account. The final-state interaction in the isospin-1 states is treated within a three-body \(\pi NN\) model approach. The main attention is paid to the possible contribution of the \(d^{*}(2380)\) dibaryon. Its influence on this reaction is compared with its role in coherent \(\pi^{0}\pi^{0}\) photoproduction on a deuteron at the same energies.
