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. $\mu$ and $\tau $, produced in association with the neutrinos. The oscillations are computed explicitly for the pion decay $\pi \to \mu+\bar{\nu}$. Leptonic decays of the $W$ are also briefly discussed.
