Abstract

The recent real time KARMEN anomaly for the electron neutrino counting rates (obtained from stopped muon decays) is analyzed by employing a neutrino flavor rotation model in which the muon neutrino is in a superposition of only two mass eigenstates. On the basis of experimental electron neutrino counting oscillations, we find a neutrino mass splitting |m₂²-m₁²|=(0.22± 0.02)(eV/c²)² and a flavor rotation angle ϕ=0.34± 0.10, both within a 95% confidence interval.
