Neutron capture cross section ratios of plutonium-240 and plutonium-242 versus gold-197 in the energy range from 50 to 250 keV
The neutron capture cross sections of /sup 240/Pu and /sup 242/Pu were measured in the energy range from 50 to 250 keV, using /sup 197/Au as a standard. Neutrons were produced via the T(p,n) reaction with the Karlsruhe 3-MV pulsed Van de Graaff accelerator. Capture events were detected by a Moxon--Rae detector. A flight path as short as 66 mm was used in the measurements to obtain a sufficient signal-to-background ratio. An overall uncertainty of 7 to 11% was obtained for /sup 240/Pu and of 10 to 15% for /sup 242/Pu. In the region of overlap between 50 and 90 keV, the presented data agree with previous results. They confirm the existing data for /sup 240/Pu. Discrepancies up to 30% for /sup 240/Pu and /sup 242/Pu were found in the evaluated ENDF/B-IV files while KEDAK 3 fits reasonably well to the experimental data.
