Abstract: (Elsevier)

Analytic formulas are derived for the QCD corrections to the electron and neutrino spectra from the weak decay of a heavy up or down type quark. The effect of the W-propagator and of the mass of the quark in the final state are incorporated. As special case the limit of local four fermion interaction, relevant for charm and bottom decays, is considered and contrasted with earlier results in the literature.
