The reaction e+e~—fir+w~K07r° has been studied over the energy range 0.64-1.40 GeV. The reaction cross section can be described well by a vector-dominance model with p( 770) and p{ 1600). Upper limits are found on the lepton width of p( 1250) and on the branching ratios for the decaysρ,ω-^π+π~π°ΐΓ0.
