Inclusive Electron Production in Multiprong Events Produced by e + e - Annihilation.

We have measured inclusive electron production in multiprong events produced by e/sup +/e/sup -/ annihilation in the center-of-mass energy range 3.9--7.4 GeV. We find the electron momentum spectra are consistent with the electrons coming mainly from decays of charmed particles, with a smaller contribution from decays of the tau lepton. From our data we calculate the average branching ratio for charmed particles to decay into an electron plus additional particles to be (8.2 +- 1.9) %.
