RESULTS FROM SAGE (THE RUSSIAN-AMERICAN GALLIUM SOLAR-NEUTRINO EXPERIMENT)

Fifteen measurements of the solar neutrino flux have been made in a ra diochemical Ga-71-Ge-71 experiment employing initially 30 t and later 57 t of liquid metallic gallium at the Baksan Neutrino Observatory bet ween January 1990 and May 1992. This provides an integral measurement of the flux of solar neutrinos and in particular is sensitive to the d ominant, low-energy p-p solar neutrinos. SAGE observed the capture rat e to be 73(+18/-16) (stat.)(+5/-7) (syst.) SNU. This represents only 5 6%-60% of the capture rate predicted by different Standard Solar Model s.
