Title: Exploratory study of fission product yield determination from photofission of ${}^{239}{Pu}$ at 11 MeV with monoenergetic photons

Abstract

Here, 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 ²³⁹Pu 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 ²³⁹Pu at E_γ = 11 MeV. In this exploratory study the yield of eight fission products ranging from ⁹¹Sr to ¹⁴³Ce has been obtained.

Monoenergetic photon-induced fission cross-section ratio measurements for ${}^{235}U$ , ${}^{238}U$ , and ${}^{239}{Pu}$ from 9.0 to 17.0 MeV

Journal Article Krishichayan, . ; Finch, S. W. ; Howell, C. R. ; ... - Physical Review C

High-accuracy data are needed to advance microscopic descriptions of the nuclear fission process, to improve the predictive precision of phenomenological models, and for applications in nuclear energy and homeland security. Purpose: In this work, the main goal is to provide high-accuracy cross-section data for photofission of ²³⁵U, ²³⁸U, and ²³⁹Pu in the energy range from the fission threshold to the high-energy tail of the giant dipole resonance. These new data should contribute significantly to the reduction of the systematic uncertainty in evaluated photofission cross-section databases. Method: Cross-section ratios for photofission of the “big three” actinide nuclei were measured using amore »« less

Erratum: Monoenergetic photon-induced fission cross-section ratio measurements for ${}^{235}U$ , ${}^{238}U$ , and ${}^{239}{Pu}$ from 9.0 to 17.0 MeV

Journal Article Finch, S. W. ; Krishichayan, . ; Howell, C. R. ; ... - Physical Review. C

In this erratum we report a correction to the previously published photofission cross-section ratio data. The actinide fission-chamber foils utilized in this work were extensively characterized during a new campaign using α- and γ-ray spectroscopy, and 2π alpha counting. These three techniques agreed, resulting in an improved accuracy of the fission-chamber foil masses used in the original experiment. The foil masses measured by α spectroscopy are detailed in Table I. All foils were counted on the same α spectrometer, using an identical geometry, which reduces the systematic uncertainty in the calculated mass ratios since the α spectrometer efficiency cancels outmore »« less

Exploratory study of fission product yields of neutron-induced fission of ${}^{235}U, {}^{238}U$ , and ${}^{239}{Pu}$ at 8.9 MeV

Journal Article Bhatia, C. ; Fallin, B. F. ; Gooden, M. E. ; ... - Physical Review C, Nuclear Physics

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 E_n = 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.

Near-barrier photofission in ${}^{232}{Th}$ and ${}^{238}U$

Journal Article Silano, J. A. ; Karwowski, H. J. - Physical Review C

A study of photofission of Th-232 and U-238 was performed by using quasimonoenergetic, linearly polarized γ-ray beams from the High Intensity γ-ray Source at Triangle Universities Nuclear Laboratory. The prompt-photofission neutron polarization asymmetries, neutron multiplicities, and the photofission cross sections were measured in the near-barrier energy range of 4.3 to 6.0 MeV. This data set constitutes the lowest energy measurements of those observables to date using quasimonoenergetic photons. Large polarization asymmetries are observed in both nuclei, consistent with the E1 excitation as observed by another measurement of this kind made in a higher-energy range.

Experiments on the synthesis of superheavy nuclei ${}^{284}{Fl}$ and ${}^{285}{Fl}$ in the ${}^{239, 240}{Pu} + {}^{48}{Ca}$ reactions

Journal Article Utyonkov, V. K. ; Brewer, N. T. ; Oganessian, Yu. Ts. ; ... - Physical Review C, Nuclear Physics

In this study, irradiations of ²³⁹Pu and ²⁴⁰Pu targets with ⁴⁸Ca beams aimed at the synthesis of Z = 114 flerovium isotopes were performed at the Dubna Gas Filled Recoil Separator. A new spontaneously fissioning (SF) isotope ²⁸⁴Fl was produced for the first time in the ²⁴⁰Pu + ⁴⁸Ca (250 MeV) and ²³⁹Pu + ⁴⁸Ca (245 MeV) reactions. The cross section of the ²³⁹Pu (⁴⁸Ca , 3 n) ²⁸⁴Fl reaction channel was about 20 times lower than predicted by theoretical models and about 50 times lower than the maximum fusion-evaporation cross section for the 3 n and 4 n channelsmore »« less
