Recent Atmospheric Neutrino Results from Soudan-2
We present atmospheric neutrino data from a 5.9 kiloton-year exposure
of the Soudan-2 iron tracking calorimeter. The observed neutrino
charged current interactions are classified as nu _mu or nu_e flavor
and the L/E_nu distributions are fitted to the hypothesis of nu_mu to
nu_x oscillations. Two independent analyses using the Feldman-Cousins
procedure result in consistent allowed regions for the oscillation
parameters Delta m^2 and sin^2(2 theta) at 90% confidence
level. Details of these analyses will be shown.
