Abstract
We report a high statistics study of the inclusive decay properties of the charmed D0 and D+ mesons, and the first inclusive study of the charmed D(s)+. The data are collected at square-root s = 3.77 GeV and square-root = 4.14 GeV with the Mark III detector at the e+e-storage ring SPEAR. For each charmed meson species, the charged-particle multiplicity, the strangeness content of the final state. and the average pi-0 multiplicity are determined.
