Event-by-Event Multiplicity Correlations in Cf(sf)
Stefano Marin, Vladimir A. Protopopescu, Ramona Vogt +7
Excited nuclear fragments are emitted during nuclear fission. The de-excitation of these fission fragments takes place as sequential emission of neutrons followed by photons. A cor…
Updating GEANIE Pu prompt -ray experimental data using modern Hauser-Feshbach fission fragment decay model
Toshihiko Kawano, Amy E. Lovell, Patrick Talou +1
We calculate fission rays for neutron-induced reactions on Pu with the Hauser-Feshbach fission fragment decay model. By applying the calculated fission rays as a…
Consideration of memory of spin and parity in the fissioning compound nucleus by applying the Hauser-Feshbach fission fragment decay model to photonuclear reactions
Toshihiko Kawano, Amy E. Lovell, Shin Okumura +3
Prompt and -delayed fission observables, such as the average number of prompt and delayed neutrons, the independent and cumulative fission product yields, and the prompt -r…
Revisiting the role of the process in the low-energy fission of U and Pu
J. Eric Lynn, Patrick Talou, Olivier Bouland
The process is reviewed in light of modern nuclear reaction calculations in both slow and fast neutron-induced fission reactions on U and Pu. Observed flu…
Deblurring fission fragment mass distributions
Pierre Nzabahimana, Amy E. Lovell, Patrick Talou
Measurements of fission fragment mass distributions provide valuable insights into the properties of fissioning systems and the dynamics of the fission process. Pre-neutron emissio…
Influence of non-statistical properties in nuclear structure on emission of prompt fission neutrons
Toshihiko Kawano, Shin Okumura, Amy E. Lovell +2
The Hauser-Feshbach Fission Fragment Decay (HFD) model is extended to calculate the prompt fission neutron spectrum (PFNS) for the thermal neutron induced fission on U,…
Solving one-dimensional penetration problem for fission channel in the statistical Hauser-Feshbach theory
Toshihiko Kawano, Patrick Talou, Stephane Hilaire
We solve the Schrödinger equation for an arbitrary one-dimensional potential energy to calculate the transmission coefficient in the fission channel of compound nucleus reactions.…
Structure in the Event-by-Event Energy-Dependent Neutron-Gamma Multiplicity Correlations in (sf)
Stefano Marin, Mustapha Stephan Okar, Eoin P. Sansevero +13
The emission of neutrons and gamma rays by fission fragments reveal important information about the properties of fragments immediately following scission. The initial fragment pro…
Correlations between energy and -ray emission in
Nathan P. Giha, Stefano Marin, James A. Baker +15
We study -ray emission following over an incident neutron energy range of MeV. We present the first experimental evidence for p…
Hauser-Feshbach fission fragment de-excitation with calculated macroscopic-microscopic mass yields
Patrick Jaffke, Peter Moller, Patrick Talou +1
The Hauser-Feshbach statistical model is applied to the de-excitation of primary fission fragments using input mass yields calculated with macroscopic-microscopic models of the pot…
U(n, f) Independent Fission Product Yield and Isomeric Ratio Calculated with the Statistical Hauser-Feshbach Theory
Shin Okumura, Toshihiko Kawano, Patrick Talou +2
We have developed a Hauser-Feshbach fission fragment decay model, HFD, which can be applied to the statistical decay of more than 500 primary fission fragment pairs (1,000 nucl…
Time Evolution of Prompt Gamma-Ray Emission in Cf(sf) and U(,f) Reactions
Patrick Talou, Amy E. Lovell, Ionel Stetcu +3
We investigate the time evolution of prompt fission emission due to the presence of ns to ms isomers in the fragments produced in the neutron-induced fission of U…
