摘要：

The contribution of intermediate vector mesons to the decays V0 --> P0P0-gamma is calculated and compared with experimental upper limits, whenever available, and previous estimates. For some decays, like phi or omega --> pi-0-pi-0-gamma our results update the existing numbers and suggest the feasibility of their experimental detection. For the decays phi-K0K0-gammaBAR and phi, omega --> pi-0-eta-gamma, we find values different from the ones in the literature and discuss the origin of the discrepancy.
