Depleted uranium was irradiated in the thermal neutron flux of the Low Intensity Test Reactor at Oak Ridge National Laboratory. From mass spectrographic analysis of Pu240 and from chemical determination of Pu content, the effective capture cross section (including both thermal and epithermal neutron capture) was determined for Np239 to be 80 ± 15 barns.
