Abstract
We report on a search for the first generation heavy neutrino that is an is osinglet under the standard SU(2)(L) gauge group. The data collected with t he L3 detector at center-of-mass energies between 130 GeV and 208 GeV are u sed. The decay channel N-e --> eW is investigated and no evidence is found for a heavy neutrino, N-e, in a mass range between 80 GeV and 205 GeV. Uppe r limits on the mixing parameter between the heavy and light neutrino are d erived. (C) 2001 Published by Elsevier Science B.V.
