Abstract

The e⁺e^- → ηγ → 7γ process was studied in the energy range 2E = 600-1060 MeV with an SND detector on a VEPP-2M e⁺e^- collider. The decay branching ratios B(φ → ηγ) = (1.353 ± 0.011 ± 0.052) × 10^-2, B(ω → ηγ) = (4.62 ± 0.71 ± 0.18) × 10^-4, and B(ρ → ηγ) = (2.73 ± 0.31 ± 0.15) × 10^-4 were measured.
