Abstract
We have determined the branching ratio of → based on the observation of 27 four-electron final state events with 0.36 estimated background event, B(→) =[3.96±0.78(stat)±0.32(syst)]×. Using the distribution of the angle between the pair decay planes, we find that the decay proceeds predominantly through the (CP=-1) state.
