Exploratory study of fission product yield determination from photofission of Pu239 at 11 MeV with monoenergetic photons

Fission product yield measurements using monoenergetic photon beams

“…While the FPYs of Wen et al [30] are in good agreement with our data, the data of Kondrat'ko et al [32] imately 25% lower. It is interesting to note that the FPY data of Bhike et al [33] agree fairly well with the present data. The data of Bhike et al [33] are normalized to the 197 Au(γ,n) 196 Au cross section.…”

“…Compared to 235 U(γ,f) and 238 U(γ,f), the number of available FPY data for 239 Pu(γ,f) is considerably smaller. Also shown in this figure are previously reported FPY data obtained in our exploratory measurement with a monoenergetic photon beam of 11.0 MeV [33].…”

“…They measured yields of about 13 fission products with half-lives in the range of our present work. In our exploratory study [33] we have measured yields of eight fission products from photofission of 239 Pu induced by monoenergetic photons at E γ = 11.0 MeV. In this exploratory work, a different approach was used to measure the photon beam flux which resulted in significantly higher uncertainties in the FPY values.…”

“…Such measurements will enable direct comparisons of the two processes. Our exploratory study [33] of photofission of 239 Pu at E γ = 11 MeV has provided data for eight fission products. The associated uncertainties were around 10-15%.…”
