  The production rates of D^*+/- mesons in charm and bottom events at
centre-of-mass energies of about 91 GeV and the partial width of primary
cc(bar) pairs in hadronic Z^0 decays have been measured at LEP using almost 4.4
million hadronic Z^0 decays collected with the OPAL detector between 1990 and
1995. Using a combination of several charm quark tagging methods based on fully
and partially reconstructed D^*+/- mesons, and a bottom tag based on identified
muons and electrons, the hadronisation fractions of charm and bottom quarks
into D^*+/- mesons have been found to be:
  f(b -> D^*+ X) = 0.173 +/- 0.016 +/- 0.012 and
  f(c -> D^*+ X) = 0.222 +/- 0.014 +/- 0.014
  The fraction of cc(bar) events in hadronic Z^0 decays,
Gamma_cc(bar)/Gamma_had = Gamma(Z^0 -> cc(bar))/Gamma(Z^0 -> hadrons), is
determined to be
  Gamma_cc(bar)/Gamma_had = 0.180 +/- 0.011 +/- 0.012 +/- 0.006
  In all cases the first error is statistical, and the second one systematic.
The last error quoted for Gamma_cc(bar)/Gamma_had is due to external branching
ratios.
