The never-ending story of missing solar neutrinos has come to an end: the deficit of approximately 50% of solar neutrinos, now confirmed by five experiments (SAGE, GALLEX, Super-Kamiokande, SNO, Davis), is explained by the detection of all three flavors in the SNO experiment using a pool filled with 1,000 tons of heavy water (deuterium) and 2 tons of table salt (sodium chloride). The SNO experiment has allowed the solar neutrino flux to be estimated at 5 million neutrinos per square centimeter per second. Of these, only exactly one-third are electron neutrinos. As expected. This also indirectly confirms the nature of fusion reactions on the Sun and provides a precise thermometer. It’s curious that in an experiment at the bottom of a deep cave, one can measure the temperature of the Sun’s core…
