Abstract
Using a sample of events collected with the CLEO II detector at the Cornell Electron Storage Ring (CESR), we measure and the partial rate in three bins of We find and Here, or but not both, and the errors are statistical, systematic, and theoretical. The method is sensitive primarily to decays with leptons in the energy range above 2.3 GeV. Averaging with the previously published CLEO results for we obtain and
