Abstract:
An experiment has been performed to test whether fission product antineutrinos will invert the electron capture decay of Ar by the reaction ClAr. Three thousand gallons of carbon tetrachloride were exposed to the high antineutrino flux from a production reactor at the Savannah River plant. The argon-37 was isolated and counted in a low level counter. The cross section for this process was found to be less than 0.25 x 10 cm, a factor of 20 below the cross section calculated assuming neutrino-antineutrino identity. The result is consistent with the principle of lepton conservation. Argon-37 was observed in the experiment produced by cosmic radiation and fast neutrons. The Ar observed in the experiment can be used to set an upper limit on the product of the solar neutrino flux and the average cross section for the neutrino capture reaction: disintegrations sec.References(0)
