Abstract

The inclusive production of η mesons at CM energies around 34 GeV has been studied for e+e− annihilation into hadrons. The average number of η-mesons per event is found to be 0.72 ± 0.10 (stat.) ± 0.18 (syst.). The abundance of η's is studied as a function of event shape parameters and it is compared to the corresponding π0 rates.
