Title: Quasielastic neutrino scattering from oxygen and the atmospheric neutrino problem

Abstract

We examine several phenomena beyond the scope of Fermi-gas models that affect the quasielastic scattering (from oxygen) of neutrinos in the 0.1--3.0 GeV range. These include Coulomb interactions of outgoing protons and leptons, a realistic finite-volume mean field, and the residual nucleon-nucleon interaction. None of these effects are accurately represented in the Monte Carlo simulations used to predict event rates due to [mu] and [ital e] neutrinos from cosmic-ray collisions in the atmosphere. We nevertheless conclude that the neglected physics cannot account for the anomalous [mu]-to-[ital e] ratio observed at Kamiokande and IMB, and is unlikely to change absolute event rates by more than 10--15 %. We briefly mention other phenomena, still to be investigated in detail, that may produce larger changes.
