/ Abstract
Abstract In the experiment with the SND detector at VEPP-2M e+e− collider the process e+e−→π+π−π0 was studied in the energy range 2E0 from 1.04 to 1.38 GeV. A broad peak was observed with the visible mass Mvis=1220±20 MeV and cross section in the maximum σ0≃4 nb. The peak can be interpreted as a ω-like resonance ω(1200).
