Abstract
A search for direct production of new leptons in the mass range from 1 0 GeV up to 225 GeV is presented by the H1 experiment at HERA. The dat a were obtained during 1993 and correspond to an integrated luminosity of 528 nb-1. The search includes heavy lepton decays to final states e (nu) gamma and e (nu) W, e (nu) Z with the subsequent decay of the W and Z bosons into jets or lepton pairs. No evidence was found for the production of new massive electrons or neutrinos in any of the decay channels. Rejection limits for excited electrons and neutrinos are der ived.
