Abstract

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