Abstract Using the ARGUS detector at thee + e − storage ring DORIS II at DESY, we have measured the inclusive production ofD 0,D + andD *(2010)+ mesons inB decays and in nonresonante + e − annihilation around 10.6 GeV. The inclusive branching ratios forB decays toD 0,D + andD *+ mesons are found to be (52.2±8.2±3.5)%, (27.2±6.3±3.5)% and (34.8±6.0±3.5)% respectively. Thus,D 0 andD + production account for about 70% of the charm produced inB decays, neglectingb→u contributions to the total width. The production cross sections and momentum spectra for continuume + e − annihilation are also presented.
