1  Dominant decay into ${{\mathit \rho}^{0}}{{\mathit \rho}^{0}}{{\mathit \pi}^{+}}$. BALTAY 1978 finds confirmation in 2 ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$2 ${{\mathit \pi}^{0}}$ events which contain ${{\mathit \rho}^{+}}{{\mathit \rho}^{0}}{{\mathit \pi}^{0}}$ and 2 ${{\mathit \rho}^{+}}{{\mathit \pi}^{-}}$.
