The Energy Spectrum of Leakage Neutrons from a Homogeneous Reactor,
Abstract
The leakage neutron spectrum from a chain reaction in an aqueous solution of uranyl nitrate has been determined for the purpose of calibrating indium foil to be used for personnel monitoring of a possible accidental critical reaction at K-25. Approximately 75% of the neutrons were found to be slow, and experimental results are in reasonable agreement with a semi-theoretical treatment of the problem. The overall cross section of indium for neutrons of all energies in this leakage spectrum was found to be about 60 +/- 4 barns. This is of the same order of magnitude as the value of 126 barns which was determined from the calculated energy spectrum using weighted averages of directly measured cross sections.
