Abstract
Small samples of U, Np, and Pu were irradiated in a focused beam of fission neutrons at the Forschungsneutronenquelle Heinz Maier-Leibnitz, FRM II in Garching, Germany. Decay measurements after irradiation revealed a number of fission products produced. Using tabulated cumulative fission yields enabled determination of integral fission cross sections of the isotopes. Cross sections (n,f) for U, Np and Pu were determined as 0.38 ± 0.04, 3.17 ± 0.25, and 2.15 ± 0.30 barn respectively. [ABSTRACT FROM AUTHOR]
