Abstract

The cross section for the e + e − → ωπ0 → π0π0γ process has been measured in the energy range of 1.1–1.9 GeV. The measurement has been made with the Spherical Neutral Detector at the VEPP-2000 e + e − collider. The data in the energy range of 1.1–1.4 GeV are in agreement with the earlier measurements with the SND and CMD-2 detectors. The cross section has also been measured above 1.4 GeV.
