Abstract The photonic part of multihadronice + e − annihilation events has been analyzed at a c.m. energy of 34 GeV. The photonic energy fraction per event is determined to bef γ=0.251±0.003 (stat.) ±0.04 (syste.). The neutral and charged components of the events are analyzed separately revealing close similarity in thrust axis directions and momentum distributions in agreement with the hypothesis that most photons result from π0 decay. π0's are reconstructed separately and used to determine the inclusive cross section. Comparing these cross sections with lower energy data from SPEAR we find some indication for scaling violation.
