Popis: The reactions e + e − → μ + μ − γ and e + e − →e + e − γ have been studied with the CELLO detector at the PETRA storage ring. Data have been collected from s =14 GeV up to 46.8 GeV . In a Dalitz plot analysis of the data, good agreement is found with QED, except for the region Mx μγ e>0.8 where the probability that QED describes the high energy data is at the percent level.
