Abstract

A lower bound on Δm2\Delta m^{2} for atmospheric neutrino oscillations can be obtained from the global value of RR at a given energy. This bound may be more reliable than one based on the observed isotropy. Some global values of RR imply an anisotropy in the neutrino flux that may, or may not be manifest in the observed neutrino interactions. A limit of Δm2>0.0077\Delta m^{2}>0.0077 eV2^{2} is easily obtained. Much higher mass scales are implied by the reported energy independence and magnitude of RR
