Abstract.
The rate of secondary charm-quark-pair production has been measured in 4.4 million hadronic Z\(^0\) decays collected by OPAL. By selecting events with three jets and tagging charmed hadrons in the gluon jet candidate using leptons and \(\mathrm{ D^{\star\pm}}\) mesons, the average number of secondary charm-quark pairs per hadronic event is found to be (3.20\(\pm\)0.21\(\pm\)0.38)\(\times10^{-2}\).
