Resumen
We point out that the usual experimental upper bounds on the "τ-neutrino mass" do not apply if neutrino mixing is considered. The suppression of the population of the τ decay spectrum near the end point, caused by mixing, may be compensated by an enhancement because of a resonant mechanism of hadronization. It is necessary therefore to analyze the whole spectrum to infer some limit to the "τ-neutrino mass." We argue that, consequently, neutrino mixing evades the objection to interpret the KARMEN anomaly as a heavy sequential neutrino. 53 5 2851 2853 Weinheimer, Ch., (1993) Phys. Lett.
