## Abstract

Muon inclusive multihadronic final states in e^{+}e^{-} annihilation at {Mathematical expression}=34.6 GeV, collected by the JADE detector at PETRA, have been analysed in terms of the semi-muonic branching ratios and fragmentation functions of heavy quarks. Defining the fragmentation variable, ζ, as {Mathematical expression} we find <z_{c}>=(77±3±5)% and <z_{b}>=(86±4±5)%. The corresponding semi-muonic branching ratios are measured to be BR(c→μv_{μ}X)=7.8±1.5±2)% and BR (b→μv_{μ}X)=(11.7±1.6±1.5)%. Defining ζ as {Mathematical expression} we observe an expected softening effect in the fragmentation due mainly to gluon emission, but find that this definition leads to semi-muonic branching ratiomeasurements which are strongly affected by uncertainties in the fragmentation process and the WCD calculation.
