英文摘要	We report on a search for the excited leptons e, mu, tau* and nu* in e(+)e(-) collisions at root s = 130-140 GeV using the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected pair produced ll in the channels ee gamma gamma, mu mu gamma gamma, tau tau gamma gamma, eeWW, and nu nu gamma gamma, We determine the lower mass limits at 95% C.L. of 64.7 GeV for e, 64.9 GeV for mu, 64.2 GeV for tau, 57.3 GeV (eW decay mode) and 61.4 GeV (nu gamma decay mode) for nu. From an analysis of the expected singly produced ll* in the channels ee gamma, mu mu gamma, tau tau gamma, nu eW and nu nu gamma, we determine upper limits on the couplings lambda/m(l) up to m(l) = 130 GeV.
