| Tóm tắt: | Title screen We present an analysis of the spectator mechanism of [delta][delta]-isobar production in the pion photoproduction on nuclei with the emission of two nucleons. The reaction mechanism is studied within the framework of the [delta]N[delta]N-correlation model, which considers the isobar and nucleon of the [delta]N[delta]N-system produced in the nucleus at the virtual NN->[delta]NNN->[delta]N transition to be in a dynamic relationship. The two-particle transition operator for nuclei is obtained by the S-matrix approach. We consider the properties of the spectator mechanism of isobar production using the example of the reaction 1616O([gamma], [nu]−pn)14([gamma], [nu]−pn)14O. Numerical estimates of the cross-section are obtained in the kinematic region, where it is possible to expect the manifestation of bound isobar-nuclear states.
