The helicity argument applied to purely leptonic decays of heavy pseudoscalar mesons (F,D) gives a high branching ratio GAMMA(F,D $Yields$ $nu$ + heavy lepton (L))/GAMMA(F,D $Yields$ $mu$ + $nu$). The branching ratio GAMMA(F $Yields$ L + $nu$)/GAMMA(F/sub $mu$3/ and F/sub e3/) is estimated to be 5--50% for the F/sub l3/ dominant eta decay mode, and GAMMA(F $Yields$ L + $nu$)/GAMMA(F $Yields$ all) is 0.3 to 1.5%.
