The hypothetical existence of η nuclei, including superlight ones (A = 3), is discussed in the light of the new data and the nuclear model with an optical potential. The quasifree photoproduction of η mesons on light nuclei is used as the basis for constructing a systematic model of η-nucleus photoproduction in reactions γ+A→N+ηA′. The dependence of the cross sections for such reactions on the main proposed properties of η nuclei is discussed, along with the final-state interaction for incident γ energies in the range from threshold to 1 GeV.
