Measurement and normalization of the relative plutonium-241 fission cross section in the thermal and low-resonance energy region. [Integrals, 50 to 0. 01 eV, cross sections]
- SCK-CEN, Mol, Belgium
The neutron-induced fission cross section of /sup 241/Pu was measured at an 8-m-long flight path of the CBNM Linac from 50 to 0.01 eV, allowing a direct normalization to the 2200 m/sec reference cross section. The fission reaction rate and the neutron flux were determined simultaneously with surface barrier detectors placed on each side of back-to-back /sup 241/Pu and /sup 10/B layers. The fission cross section was calculated assuming a 1/v behavior of the /sup 10/B(n,..cap alpha..)/sup 7/Li cross section. Several fission and resonance integrals were calculated from the normalized sigma/sub f/ versus energy curve and compared with other results. Also, the 20.44/sup 0/C Westcott factor, g/sub f/, was calculated to be 1.046 +- 0.006.
