Abstract
The decay has been studied with the CLEO II detector at the Cornell Electron Storage Ring. The branching fraction is measured to be . The result is in good agreement with the isospin expectation but somewhat below the conserved-vector-current prediction. We have searched for resonance substructure in the decay. Within the statistical precision, the decay is saturated by the channels , , and . This is the first observation of this ω decay mode and the branching fraction is measured to be .
