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 to46.8GeV. In a Dalitz plot analysis of the data, good agreement is found with QED, except for the region Mxμγe>0.8 where the probability that QED describes the high energy data is at the percent level.
