Abstract
The total and differential cross sections of the process e(+)e(-) --> n gam ma with n greater than or equal to 2 are measured using data collected by t he L3 experiment at centre-of-mass energies of root s = 183 and 189 GeV, Th e results are in agreement with the Standard Model expectations. Limits are set on deviations from QED, contact interaction cut-off parameters and mas ses of excited electrons. (C) 2000 Published by Elsevier Science B.V. All r ights reserved.
