Search for Neutrinos from the Sun

A search was made for solar neutrinos with a detector based upon the reaction Cl^37 (, e^-) Ar^37. The upper limit of the product of the neutrino flux and the cross sections for all sources of neutrinos was 310^-36 sec^-1 per Cl^37 atom. It was concluded specifically that the flux of neutrinos from B^8 decay in the sun was equal to or less than 210^6 cm^-2 sec^-1 at the earth, and that less than 9% of the sun's energy is produced by the carbon-nitrogen cycle.
