| The discovery of neutrino oscillations, and hence neutrino mass, in both solar and atmospheric neutrinos has been one of the major recent advances in particle physics. Among the many experiments that contributed to the study of this phenomenon. Super-Kamiokande is regarded as the experiment having established neutrino oscillations using atmospheric neutrinos. The final data sample of 5.90 kiloton-year exposure collected by the Soudan 2 detector is studied for the effects of atmospheric neutrino oscillations. These data are analyzed with a maximum likelihood analysis of the neutrino L/ E distribution using the Feldman-Cousins approach. The result confirms the discovery of oscillations in atmospheric neutrinos. |
