Production of P-wave charm and charm-strange mesons in hadronic Z{sup 0} decays

Measurements of the production rates of the

Z

decays are presented based on an analysis of over 4 million events recorded using the OPAL detector at LEP. These rates are determined separately for production in charm fragmentation and in the inclusive decays of bottom flavoured hadrons. The

decays.
