Abstract

We study the effect of matter enhanced neutrino oscillations on atmospheric neutrinos. A recently proposed solution to the solar neutrino problem with Δm2 = 1.1×10-4 eV2 suggests enhanced effects in the range 200 MeV-500MeV. We find no evidence of this effect for vμ↔ve mixing. Limits are set on the magnitude of the mixing angle. Our limit is sin θ v< 0.14 at 90% confidence level. The limit is dominated by statistical errors and may be improved.
