To study the isotopic structure of the amplitude of the photoexcitation of the S11(1535) resonance, the cross sections for the reaction d(γ, η)np are calculated with allowance for the final-state rescattering of η mesons and for the formation of an η meson via the photoproduction of an intermediate pion. From comparison of our results with experimental data, it was found that α = T(0)/Tp = 0.076. This value is in agreement with the predictions of quark models.
