keV capture cross section of /sup 242/Pu. [5 to 70 keV]

The neutron capture cross section of /sup 242/Pu has been measured from 5 to 70 keV. The high-low bias method was used to distinguish between capture and fission events. Transmission experiments were also made in the resonance region. A normalization method was developed using the absorption and transmission data from six resonances. Using an average s-wave radiation width of 22 MeV, an s-wave strength function of 1.16 x 10/sup -4/ and our measured capture cross section, we have determined p-wave contributions to the /sup 242/Pu capture cross section below 70 keV. 1 figure, 2 tables.
