Abstract
The decay branching fractions of the three narrow resonances to have been measured by analyzing about data collected with the CLEO III detector. The branching fraction is consistent with the current world average, but and are significantly larger than prior results. These new muonic branching fractions imply a narrower total decay width for the and resonances and lower other branching fractions that rely on these decays in their determination.
