摘要：

The e(+)e(-) --> pi(0)pi(0)gamma reaction was studied in the energy range 0.36-0.97 GeV on a VEPP-2M e(+)e(-) collider with an SND detector. The decay probabilities were found to be B(omega --> pi(0)pi(0)gamma) = (7.8 +/- 2.7 +/- 2.0) x 10(-5) and B(rho --> pi(0)pi(0)gamma) = (4.8(-1.8)(-)(+3.4) +/- 0.2) x 10(-5).
