OSTI ID:7148792
The author reports results on the differential and total cross sections for inclusive production of the charmed particles D/sup *+/, D/sup *0/, D/sup 0/, D/sup +/, D/sub s/, and ..lambda../sub c/ in e/sup +/e/sup -/ annihilations at root s = 10.55 GeV. Relevant quark fragmentation models are compared with the measured charmed particle distributions. We measure B(D/sup *+/ ..-->.. D/sup 0/..pi../sup +/) = 0.52 +/- 0.07 +/- 0.11.
