The cross section of the process e+e-→ωπ0→ π0π0γ has been measured in the c.m. energy range 920-1380 MeV with the CMD-2 detector. Its energy dependence is well described by the interference of the ρ(770) and ρ(1450) mesons decaying to ωπ0. Upper limits for the cross sections of the direct processes e+e-→π0π0γ, ηπ0γ have been set. © 2003 Elsevier Science B.V. All rights reserved.
