Energy-Resolved Spin and Parity Distributions of Fission Fragments
Petar Marević, Nicolas Schunck, Antonio Bjelčić +1
Fission fragments are born rotating rapidly, but the evolution of this spin with excitation energy and its impact on fission observables remain largely unknown. Combining state-of-…
An exact time-dependent generator coordinate method with projection for spontaneous fission reactions

Microscopic descriptions of fission dynamics through the barrier rely on different theoretical frameworks depending on the fission regime, with the time-dependent generator coordin…
Microscopic Spin-Parity Distributions of Fission Fragments
Guillaume Scamps, Petar Marević, Antonio Bjelčić +1
Recent microscopic studies have investigated various features of the spin distributions of fission fragments, but their parity distributions remain largely unexplored. In this Lett…
Pair Transfer and Reaction Dynamics in Ca + Zr Collisions Below the Coulomb Barrier
Ibrahim Abdurrahman, Andrzej Makowski, Guillaume Scamps +2
Sub-barrier fusion reactions are ideal for probing the effects of pairing correlations on simultaneous neutron transfer. Previous calculations using the BCS approximation showed an…
The advanced evolution of massive stars: I. New reaction rates for carbon and oxygen nuclear reactions
T. Dumont, A. Bonhomme, A. Griffiths +9
The nuclear rates for reactions involving 12C and 16O are key to compute the energy release and nucleosynthesis of massive stars during their evolution. These rates shape the stell…
Spatial orientation of the fission fragment intrinsic spins and their correlations
Guillaume Scamps, Ibrahim Abdurrahman, Matthew Kafker +2
New experimental and theoretical results obtained in 2021 made it acutely clear that more than 80 years after the discovery of nuclear fission we do not understand the generation a…
Skyrme-Hartree-Fock-Bogoliubov mass models on a 3D mesh: III. From atomic nuclei to neutron stars
Guilherme Grams, Wouter Ryssens, Guillaume Scamps +2
We present BSkG3, the latest entry in the Brussels-Skyrme-on-a-grid series of large-scale models of nuclear structure based on an energy density functional. Compared to its predece…
Generation, dynamics, and correlations of the fission fragments' angular momenta
Guillaume Scamps, George Bertsch
The generation of angular momentum in fissioning nuclei is not well understood. The predictions of different models disagree, particularly concerning the correlation between the fr…

Wouter Ryssens, Guillaume Scamps, Stephane Goriely +1
Large-scale models of nuclear structure are currently the only way to provide consistent datasets for the many properties of thousands of exotic nuclei that are required by nucleos…
The mass of odd-odd nuclei in microscopic mass models
W. Ryssens, G. Scamps, G. Grams +3
Accurate estimates of the binding energy of nuclei far from stability that cannot be produced in the laboratory are crucial to our understanding of nuclear processes in astrophysic…
Progress on Brussels-Skyrme atomic mass models on a grid: stiff neutron matter equation of state
Guilherme Grams, Wouter Ryssens, Guillaume Scamps +2
We report here the current developments on the Brussels-Skyrme-on-a-Grid (BSkG) atomic mass models. In comparison with our previous models, BSkG3 improves the infinite nuclear matt…
Microscopic description of the torque acting on fission fragments
Guillaume Scamps
When two fragments are created in a fission decay, any torque due to nuclear and Coulomb interaction can change the fragment's angular momentum. This article explores the character…

Wouter Ryssens, Guillaume Scamps, S. Goriely +1
Models based on nuclear energy density functionals can provide access to a multitude of observables for thousands of nuclei in a single framework with microscopic foundations. Such…

Guillaume Scamps, Stephane Goriely, Erik Olsen +2
The modeling of nuclear reactions and radioactive decays in astrophysical or earth-based conditions requires detailed knowledge of the masses of essentially all nuclei. Microscopic…

A regular pattern, revealing the leading role of the light-fragment nuclear charge, is found to emerge from a consistent analysis of the experimental information collected recently…
Future of Nuclear Fission Theory
Michael Bender, Remi Bernard, George Bertsch +30
There has been much recent interest in nuclear fission, due in part to a new appreciation of its relevance to astrophysics, stability of superheavy elements, and fundamental theory…
Effect of Octupole correlations on Fission of Light Nuclei
