The charged particle multiplicity distributions for single jets in e/sup +/e/sup -/ annihilation at 29 GeV have been measured using the High Resolution Spectrometer at PEP. The shape of the distribution agrees well with a Poisson distribution. No correlation is observed between the multiplicities in the two jets of an event. For fixed values of the prong number of the total event, the multiplicity sharing between the two jets is in good agreement with a binomial distribution. These observations are contrasted to the results from soft hadronic collisions and conclusions are drawn about the nature of clusters. 21 refs., 4 figs.
