Title: Exploratory study of fission product yields of neutron-induced fission of U235, U238, and Pu239 at 8.9 MeV

Using dual-fission chambers each loaded with a thick (200–400–mg/cm2) actinide target of 235,238U or 239Pu and two thin (~10–100–μg/cm2) reference foils of the same actinide, the cumulative yields of fission products ranging from 92Sr to 147Nd have been measured at En = 8.9MeV. The 2H(d,n) 3He reaction provided the quasimonoenergetic neutron beam. Here, the experimental setup and methods used to determine the fission product yield (FPY) are described, and results for typically eight high-yield fission products are presented.
