Abstract
In the experiment with the SND detector at VEPP-2M e^+e^- collider the process $e^+e^-\toÏ^+Ï^-Ï^0$ was studied in the energy range 2E_0 from 1.04 to 1.38 GeV. A broad peak was observed with the visible mass $M_{vis}=1220\pm 20$ MeV and cross section in the maximum $Ï_0\simeq 4$ nb. The peak can be interpreted as a $Ï$-like resonance $Ï(1200)$.
