摘要：

The e(+)e(-) --> pi(0)pi(0)gamma process was studied in the SND experiment at VEPP-2M e(+)e(-) collider in the energy region 0.60-0.97 GeV. From the analysis of the energy dependence of measured cross section the branching ratios B(omega --> pi(0)pi(0)gamma) = (6.6(-0.8)(+1.4) +/- 0.6) x 10(-5) and B(rho --> pi(0)pi(0)gamma) = (4.1(-0.9)(+1.0) +/- 0.3) x 10(-5) were obtained.
