Abstract

We report a new measurement of the B-meson semileptonic decay momentum spectrum that has been made with a sample of 9.4 [Formula Presented] of [Formula Presented] data collected with the CLEO II detector at the [Formula Presented] resonance. Electrons from primary semileptonic decays and secondary charm decays were separated by using charge and angular correlations in [Formula Presented] events with a high-momentum lepton and an additional electron. We determined the semileptonic branching fraction to be [Formula Presented] from the normalization of the electron-energy spectrum. We also measured the moments of the electron-energy spectrum with minimum energies from 0.6 to 1.5 GeV.
