Abstract
A search for heavy neutrinos that are isosinglets under the standard SU(2)( L) gauge group is made at center-of-mass energies 130 < root s < 189 GeV wi th the L3 detector at LEP. Such heavy neutrinos are expected in many extens ions of the Standard Model. The starch is performed for the first generatio n heavy singlet neutrino, N-e, through the decay mode N-e --> e + W, We set upper limits on the mixing parameter between the heavy and light neutrino for the heavy neutrino mass range from 80 GeV to 185 GeV.
