Title: Atmospheric Neutrinos in Soudan 2
Abstract: Soudan 2 has measured the atmospheric neutrino flavor ratio with4.2 fiducial kiloton-years of exposure. It measures a flavorratio of $0.66 \pm 0.11(stat)$, inconsistent with the expectedratio but consistent with the hypothesis of neutrino oscillationsand the Super-Kamiokande data. In a sample of events with goodangular resolution, fits to the L/E distribution suggest that$\Delta m^2 > 10^{-3}eV^2$.
