The total and differential cross sections of the process e+e−→nγ with n≥2 are measured using data collected by the L3 experiment at centre-of-mass energies of and . The results are in agreement with the Standard Model expectations. Limits are set on deviations from QED, contact interaction cut-off parameters and masses of excited electrons.
