Exploratory study of fission product yield determination from photofission of Pu 239 at 11 MeV with monoenergetic photons


Journal Article

© 2017 American Physical Society. Measurements of fission product yields play an important role for the understanding of fundamental aspects of the fission process. Recently, neutron-induced fission product-yield data of Pu239 at energies below 4 MeV revealed an unexpected energy dependence of certain fission fragments. In order to investigate whether this observation is prerogative to neutron-induced fission, a program has been initiated to measure fission product yields in photoinduced fission. Here we report on the first ever photofission product yield measurement with monoenergetic photons produced by Compton back-scattering of FEL photons. The experiment was performed at the High-Intensity Gamma-ray Source at Triangle Universities Nuclear Laboratory on Pu239 at Eγ=11 MeV. In this exploratory study the yield of eight fission products ranging from Sr91 to Ce143 has been obtained.
