Coherent -meson photoproduction from nuclei is considered within an extended analogue of the -hole model taking into account the configuration mixing of baryon-hole excitations of different sorts of baryons. Calculated integrated and differential cross-sections for reactions and demonstrate the important role of the exchange interaction between intermediate D13(1520)-hole and S11(1535)-hole excitations.
