A Novel Kind of Neutrino Oscillation Experiment

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 ${\bar{\nu }}_e{e}^{-}\to {\bar{\nu }}_e{e}^{-}$. 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.
