SKAM multi-GeV
1  ASHIE 2005 results are based on an exposure of 92 kton yr during the complete Super-Kamiokande I running period. The analyzed data sample consists of fully-contained single-ring ${{\mathit e}}$ -like events with visible energy $>$ 1.33 GeV. Upward-going events are those with $-1$ $<$ cos(zenith angle) $<$ $-0.2$ and downward-going events are those with 0.2 $<$ cos(zenith angle) $<$ 1. The ${{\mathit e}}$ -like up-down ratio for the multi-GeV data is consistent with 1 (the expectation for no atmospheric ${{\mathit \nu}_{{e}}}$ oscillations).
