MASS OR GRAVITATIONALLY-INDUCED NEUTRINO OSCILLATIONS - A COMPARISON OF B-8 NEUTRINO FLUX SPECTRA IN A 3-GENERATION FRAMEWORK

Both gravitational and mass induced neutrino oscillation mechanisms pr ovide possible resolutions to the solar neutrino problem. The distingu ishing feature between the two mechanisms is their dependence on the n eutrino energy. We investigate the implications of this by computing t he B-8 neutrino spectrum as determined from each mechanism using a rea listic three-flavor evolution model. We find that in the limit of smal l theta(13) mixing angle, the differences are significant enough to ob serve in future solar neutrino experiments.
