Solar Neutrino Problem As shown in the animation describing the proton-proton chain above, the number of neutrinos produced in the Sun is directly proportional to the number of nuclear reactions that are taking place in the Sun's core. The same can also be said of the number of neutrinos produced via the Carbon-Nitrogen-Oxygen chain. The more reactions there are, the more neutrinos are produced and the more that should be detected here on the Earth. The number of neutrinos detected coming from the Sun was smaller than expected. Early experiments detected only 1/3 to 1/2 of the expected number of neutrinos. These experiments used hundreds of thousands of liters of cleaning fluid (composed of chlorine compounds) or very pure water. They were sensitive to the high-energy neutrinos produced in less than one percent of the nuclear fusion reactions. Later experiments using many tons of gallium were able to detect the more abundant low-energy neutrinos. However, those experiments also found the same problem---too few neutrinos (the gallium experiments found about 2/3 the expected number). The puzzling lack of neutrinos from
