Attempt to Detect the Antineutrinos from a Nuclear Reactor by the 37Cl( anti-νe,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( anti-νe,e)37Ar with fission product antineutrinos. The experiments serve to place an upper limit on the antineutrino capture cross section for the reaction of 2·10-42 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.
