Looking for oscillations

Abstract A search is performed for the antineutrino oscillation process ν μ → ν τ with 15' bubble chamber data. Assuming maximal mixing, we obtain for the neutrino mass difference parameter Δ 2 (90% c.1.). Alternatively, for Δ > 16 eV 2 the transition probability is found to be less than 0.022 (90% c.1.).
