An analysis of the effective polarization of the ∆++ isobar formed in a nucleus as a result of the virtual transition pp→∆++ n, and manifested in the reaction 16O(γ, π+ p)15C , is performed. The polarization of the isobar is analyzed within the framework of the ∆N correlation model of the A(γ, πN)B reaction, which takes account of the dynamic coupling between the isobar and a nucleon of the system ∆++ n .
