Attempt to Detect the Antineutrinos from a Nuclear Reactor by the 37Cl(e,e)37Ar Reaction
Phys. Rev. 97 (1955) 766;

Abstracts
Tanks containing 200 and 3900 liters of carbon tetrachloride were irradiated outside of the shield of the Brookhaven reactor in an attempt to induce the reaction 37Cl(e,e)37Ar with fission product antineutrinos. The experiments serve to place an upper limit on the antineutrino capture cross section for the reaction of 210-42 cm2 per atom. Cosmic ray induced 37Ar was observed and production rate measured at 14100 feet altitude and sea level. Measurements with the 3900-liter container shielded from cosmic rays with 19 feet of earth permit placing an upper limit on the neutrino flux of the sun.
