Abstract
The differential neutron-induced fission cross section of 245Cm was measured from 0.01 to 35 eV at the Lawrence Livermore Laboratory 100-MeV electron Linac using ∼6 µg of 245Cm. The energy dependence of the cross section is non-1/v below 1 eV due mainly to a bound level. Normalizing to previous integral data, a thermal (2200 m/s) fission cross section of 2143 ± 58 b is obtained. Resonance parameters were extracted and are compared to previous results. Calculated values of the resonance integrals for fission and capture using these parameters are in good agreement with previous measurements.Keywords
