Abstract: (Elsevier)

The cross section of the process e + e − → ωπ 0 → π 0 π 0 γ 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 ωπ 0 . Upper limits for the cross sections of the direct processes e + e − → π 0 π 0 γ , ηπ 0 γ have been set.

Note:
