We report a new measurement of the B-meson semileptonic decay momentum spectrum that has been made with a sample of 9.4 fb(-1) of e(+)e(-) data collected with the CLEO II detector at the Y(4S) resonance. Electrons from primary semileptonic decays and secondary charm decays were separated by using charge and angular correlations in Y(4S) events with a high-momentum lepton and an additional electron. We determined the semileptonic branching fraction to be B(B-->Xe(+)nu(e))=(10.91+/-0.09+/-0.24)% 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.
