We point out the importance of two-body final states of weak isosinglet neutral heavy leptons predicted in several models of new physics beyond the standard model. We concentrate on muon-type neutral heavy leptons L{sub {mu}}{sup 0} with a mass M{lt}2 GeV that can be searched for with increased sensitivity at a new round of neutrino experiments at CERN and Fermilab. Providing explicit decay rate formulas for the ee{nu}, e{mu}{nu}, {mu}{mu}{nu}, {pi}{mu}, {rho}{mu}, and a{sub 1}{mu} final states, we use general scaling features to estimate the sensitivity of L{sub {mu}}{sup 0} searches in current and future experiments, emphasizing the importance of the {pi}{mu} decay mode. {copyright} {ital 1997} {ital The American Physical Society}
