Relative yields of xenon isotopes in the photofission of237Np and235U

Fission product yield measurements using monoenergetic photon beams

“…There exist quite a number of bremsstrahlung-beaminduced FPY measurements for the 235 U(γ,f) reaction in the energy range of E γ ∼ 10.0 -20.0 MeV. Most of these experiments were carried out during the 1970s by Kondrat'ko et al [12,15], Petrzhak et al [13,16], Aumann et al [14], and Thierens et al [17]. In 1980 Jacobs et al [18] measured and compared the mass chain yield Our FPY data obtained with a monoenergetic photon beam at 13.0 MeV are compared in Fig.…”
