Abstract
The inclusive production rates and differential cross-sections of phot ons and mesons with a final state containing photons have been measure d with the OPAL detector at LEP. The light mesons covered by the measu rements are the pi(0), eta, rho(770)(+/-), omega(782), eta'(958) and a (0)(980)(+/-). The particle multiplicities per hadronic Z(0) decay, ex trapolated to the full energy range, are: [n(gamma)] = 20.97 +/- 0.02 +/- 1.15, [n(pi 0)] = 9.55 +/- 0.06 +/- 0.75, [n(eta)] = 0.97 +/- 0.03 +/- 0.11, [n(p+/-)] = 2.40 +/- 0.06 +/- 0.43, [n(omega)] = 1.04 +/- 0 .04 +/- 0.14, [n(eta')] = 0.14 +/- 0.01 +/- 0.02, [n(a0+/-)] = 0.27 +/ - 0.04 +/- 0.10, where the first errors are statistical and the second systematic. In general, the results are in agreement with the predict ions of the JETSET and HERWIG Monte Carlo models.
