Examination on SK atmospheric neutrino experiment by the computer   experiment
  We examine neutrino events occurring inside the SuperKamiokande (SK) detector and those occurring outside the same detector using computer simulations. We analyze the zenith angle distribution of Fully Contained Events and show the method for the determination of the incident neutrino by the SK group is unreliable. The analysis of the neutrino events occurring outside the detector shows these events agree with the Monte Carlo simulation without oscillation.
