    abstract = "During the last 1995 data acquisition period at LEP, the DELPHI
experiment collected an integrated luminosity of 5.9 pb(-1) at
centre-of-mass energies of 130 GeV and 136 GeV. Radiative leptonic
events (e, mu, tau) With high energy photons were studied and compared
to Standard Model predictions. The data were used to search for charged
excited leptons decaying through an electromagnetic transition. No
significant signal was found. From the search for pair produced excited
leptons, the limits m(e)* > 62.5 GeV/c(2), m(mu)* > 62.6 GeV/c(2)
and m(tau)* > 62.2 GeV/c(2) at 95% confidence level were established.
For single excited lepton production, upper limits on the ratio
lambda/m(l)* of the coupling of the excited charged lepton to its mass
were derived."
