  A novel method to look for neutrino oscillations is proposed based on the
elastic scattering process $\bar{\nu}_{i} e^{-}\rightarrow \bar{\nu}_{i}
e^{-}$, taking advantage of the dynamical zero present in the differential
cross section for $\bar{\nu}_{e} e^{-}\rightarrow \bar{\nu}_{e} e^{-}$. An
effective tunable experiment between the "appearance" and "disappearance"
limits is made possible. Prospects to exclude the allowed region for
atmospheric neutrino oscillations are given.
