摘要：

The e(+)e(-) --> eta gamma --> 7 gamma 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(phi --> eta gamma) = (1.353 +/- 0.011 +/- 0.052) x 10(-2), B(omega --> eta gamma) = (4.62 +/- 0.71 +/- 0.18) x 10(-4), and B(rho --> eta gamma) = (2.73 +/- 0.31 +/- 0.15) x 10(-4) were measured.
