This research aims to measure the solar neutrino capture rate using metallic gallium and compare it to predictions.
Conducted the Russian-American Gallium Experiment (SAGE) from January 1990 to December 1997
Extracted germanium from gallium for neutrino detection
Performed statistical and systematic data analysis
Measured solar neutrino capture rate of 67.2 SNU with uncertainties of -7.0/-3.0 and +7.2/+3.5
The measured rate is about half of the predicted standard solar model rate of 129 SNU
