New tools for solving the solar neutrino problem.
01 January 1986
Neutrino (nu) excitation of nuclear levels (NUEX) via neutral currents is shown to be crucially important to the solar-nu problem as a method of detecting nu's regardless of flavor. We examine (11)B, (40)Ar and (35)Cl as NUEX targets. The (11)B system offers means for concurrent solar-nu-spectroscopy by NUEX and by charged-current nu(e)-capture with a set of differing thresholds. It promises a self-contained solution to the solar-nu problem as well as key probes for revealing the structure of resonant flavor and non-flavor nu-oscillations in the sun. This approach may be feasible in an ICARUS-type underground experiment.
