The Mark II detector in the ee− storage ring PEP at the Stanford Liner Accelerator Center (SLAC) is used to measure selected properties of hadronic events corresponding to produced bottom or charm quarks. Heavy flavor enrichment is accomplished by tagging events with prompt electrons or muons. Differences between bottom, charm and average jets are observed for momentum, transverse momentum, rapidity and jet mass distributions. A detailed study of the charged multiplicity of b- and c-enriched events finds the mean multiplicity of bottom and charm events to be 16.2 +- 0.5 +- 1.0 and 13.2 +- 0.5 +- 0.9, respectively, where the first error is statistical and the second is systematic. The corresponding 'non-leading' multiplicities of charged particles accompanying the pair of heavy hadrons are 5.2 +- 0.5 +- 0.9 for bottom, and 8.0 +- 0.5 +- 0.9 for charm. We find from these non-leading multiplicities that bottom and charm hadrons fragment with mean energy fractions of z/sub b/ = 0.79/sub -0.05//sup +0.10/ and z/sub c/ = 0.60/sub -0.11//sup +0.09/. These results confirm the expected hard fragmentation of heavy quarks and agree with previous measurements based on leptonic inclusive spectra and D* fragmentation. 48 refs., 29 figs.
