Abstract
We consider the impact of
hadronic corrections to
the energy spectrum of the decay electron in muon decay. We find that
the correction can be described, within good approximation, by a linear
function in the electron energy. Explicit expressions for the form
factors needed in an approach based on dispersion integrals are given.
