Abstract
The possibility of detecting single heavy Dirac and/or Majorana
neutrinos at LEP II is investigated
for heavy neutrino masses in the range
MN=(s1/2/2,s1/2).
We study the process
as a clear signature
for heavy neutrinos.
Numerical estimates for cross sections and distributions for
the signal and the background are
calculated and a Monte Carlo reconstruction of final state particles
after hadronization is
presented.
