Abstract

If neutrino oscillations in the solar interior are responsible for the suppressed 8B flux measured by the Homestake 37Cl experiment and the Kamiokande II water Cerenkov detector, then a comparison of the gallium, chlorine, and water results may make possible a determination of the neutrino mass difference and mixing angle. Present experimental results disfavor a neutrino oscillation solution with large neutrino mass differences, but cannot yet be used to choose among a variety of lower mass oscillation solutions and oscillations coupled with nonstandard solar models. In particular, although nonstandard solar models with elevated core temperatures have received little attention, there are theoretical justifications for such models, and the expected counting rates from such models coupled with neutrino oscillations can give results entirely con-sistent with the observations.
