    abstract = "A search with the DELPHI detector at LEP for excited leptons (e*,
mu*, tau* and nu*) decaying through gamma, W or Z transitions is
reported. The data used correspond to an integrated luminosity of 10
pb(-1) e(+)e(-) centre-of-mass energy at an e of 161 GeV. The search for
pair produced excited leptons established the limits m(e)* > 79.6
GeV/c(2), m(mu)* > 79.6 GeV/c(2), m(tau)* 79.4 GeV/c(2) and m(nu)*
> 56.4 GeV/c(2) at 95% confidence level, assuming that the SU(2) and
U(I) couplings of excited leptons are in the same ratio as for normal
leptons and considering both left and right-handed components. Limits
corresponding to other assumptions are also given. The search for single
excited lepton production established upper limits on the ratio
lambda/m(l)* of the coupling of the excited lepton to its mass."
