Abstract
Problems long present in the conventional formalism employed for
neutrino oscillations are discussed. We here develop a more satisfactory
framework based on the Dirac equation and its propagators.
When 4-momentum conservation is strictly enforced, there will
be induced oscillations in space (but not between generations) for
the charged leptons, e.g. 
and 
, produced in association
with the neutrinos. The oscillations are computed explicitly for the
pion decay 
. Leptonic decays of the W are also
briefly discussed.
