 Soviet–American Gallium Experiment

The Soviet–American Gallium Experiment was an international scientific collaboration conducted in the late 1980s and early 1990s, specifically designed to investigate the properties of neutrinos emitted by the Sun. This experiment was part of an effort to understand the solar neutrino problem, which involved discrepancies between theoretical predictions of solar neutrino production and the actual number of neutrinos detected on Earth. The experiment utilized gallium as a detector material.
