Description
A number of experiments using neutrino sources were conducted with the intention of examining the systematics of radiochemical solar neutrino measurements of the last century. The results differed from expectations leading to the so-called gallium anomaly. This anomaly can be stated: “The measurements of the charged-current capture rate of neutrinos on Ga-71 from strong radioactive sources have yielded results below those expected, based on the known strength of the principal transition supplemented by theory”. This mystery deepened with results from the Baksan Experiment on Sterile Transitions (BEST). The results these experiments and the proposals for other similar studies will be summarized with an emphasis on BEST, which used a 3.414-MCi Cr-51 sample to test the gallium anomaly.
