Abstract
A search for neutral heavy leptons (NHLs) has:been performed using an instr umented decay channel at the NuTeV (E-815) experiment at Fermilab. The data were examined for NHLs decaying into muonic final states (mu mu v, mu ev, mu pi, and mu p); no evidence has been found for NHLs in the 0.25-2.0 GeV m ass range. This analysis places limits on the mixing of NHLs with standard light neutrinos at a level up to an order of magnitude more restrictive tha n previous search limits in this mass range.
