Fission Product Yields from Neutron-Induced Fission of Major Actinides at 6.5 MeV

ORAL

Abstract

Fission product yields (FPY) are an important observable for fundamental and applied nuclear physics. We are conducting a comprehensive study of the cumulative FPY from neutron-induced fission of 235U, 238U, and 239Pu between 0.5 and 15 MeV at the Triangle Universities Nuclear Laboratory. Actinide foils are irradiated by monoenergetic neutron beams produced with a tandem accelerator. A dual fission chamber is employed to determine the number of fission events induced in the target. After irradiation the samples are assayed using high-purity germanium detectors in a low-background counting facility to identify and determine the yield of fission products. Details of the experiment setup and preliminary results for FPY at a neutron energy of 6.5 MeV will be presented.
