Abstract
Excited electrons, e*'s, have been searched for by making use of the processes e+e-→e+e-γγ and eγ(e) (quasi-real Compton scattering). From the former process, we have obtained the lower limit for the mass of e*', 27.9 GeV/c. A good agreement with QED is observed in the latter process, and new upper limits have been set for the coupling strength λ as a function of the mass of e*.
