Abstract
We have measured the fission cross-section ratios 240Pu:235U, 242Pu:235U, and 244Pu:235U as a function of neutron energy from 0.1 to 30 MeV using ionization fission chambers, the time-of-flight technique, and the threshold method at the Lawrence Livermore Laboratory 100-MeV electron linear accelerator. The measured cross-section ratios, averaged over the neutron energy interval from 1.75 to 4.00 MeV, are 1.366 ± 0.025, 1.110 ± 0.019, and 0.979 ± 0.020, respectively.Keywords
