Search for Neutrinos from the Sun

摘要: A search was made for solar neutrinos with a detector based upon the reaction ${\mathrm{Cl}}^{37}(\ensuremath{\nu}, {e}^{\ensuremath{-}}){\mathrm{Ar}}^{37}$. The upper limit of product neutrino flux and cross sections all sources 3\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}36}$ ${\mathrm{sec}}^{\ensuremath{-}1}$ per ${\mathrm{Cl}}^{37}$ atom. It concluded specifically that from ${\mathrm{B}}^{8}$ decay in sun equal to or less than 2\ifmmode\times\else\texttimes\fi{}${10}^{6}$ ${\mathrm{cm}}^{\ensuremath{-}2}$ at earth, 9% sun's energy is produced by carbon-nitrogen cycle.
