Solar neutrinos.
Abstract
Studies of solar neutrinos as a tool to understanding the evolution and working nuclear processes in the interiors of stars are reviewed. Fusion reaction models for stellar interiors are described, noting the 0.81 MeV proton-proton reaction which produces neutrinos, and the Brookhaven experiment designed to study reactions produced by solar neutrino capture. A neutrino was posited to be captured by Cl-37 to yield Ar-37 and an electron. The experiment involved a 400,000 l tank of perchloroethylene situated 1500 m underground to shield from cosmic rays. Insufficient neutrinos were detected to establish a distinction from cosmic ray neutrinos. Further experiments comprising counting from Ga-71, Rb-87, In-115, and Tl-205 reactions occurring from solar proton-proton and proton + electron + H2 + nu reactions are outlined, and are shown to be dependent on conservation of electric charge. Finally, the detection of stellar collapses is discussed.
