摘要：

The cross section of the process e(+)e(-) --> eta gamma has been measured in the 600-1380 MeV c.m. energy range with the CMD-2 detector. The following branching ratios have been determined: B(rho --> eta gamma) = (3.28 +/- 0.37 +/- 0.23) x 10(-4), B(omega --> eta gamma) = (5.10 +/- 0.72 +/- 0.34) x 10(-4). B(phi --> eta gamma) = (1.287 +/- 0.013 +/- 0.063) x 10(-2). Evidence for the rho (1450) --> eta gamma decay has been obtained for the first Lime. (C) 2001 Published by Elsevier Science B.V.
