Exact solution of adiabatic time dependent Hartree-Fock-Bogoliubov inertia for fission
C. V. Nithish Kumar, Gabriel Martínez-Pinedo, Samuel A. Giuliani +1
An efficient method to exactly compute the adiabatic time-dependent Hartree-Fock-Bogoliubov collective vibrational inertias typical of fission is proposed. The method uses the quas…
Microscopic pairing in fission dynamics
A. Zdeb, A. Baran, S. A. Giuliani +2
Nuclear fission can be modelled as a quantum tunneling process driven by the interplay between the nuclear binding energy and the collective inertia. Within the Wentzel-Kramers-Bri…
Pairing in fission: Mean-field and collective inertias study
A. Zdeb, M. Warda, L. M. Robledo +1
Pairing plays a crucial role in the microscopic description of nuclear fission. Microscopic methods provide access to three quantities related to pairing, namely, the pairing gap (…
Impact of nuclear masses on r-process nucleosynthesis: bulk properties versus shell effects
Samuel A. Giuliani, Gabriel Martínez-Pinedo, Andreas Bauswein +1
We investigate the impact of the model estimating the masses of exotic nuclei on r-process nucleosynthesis, assessing the dependence of the abundance distribution on the specific p…
Cluster properties of heavy nuclei predicted with the Barcelona-Catania-Paris-Madrid energy density functional
Samuel A. Giuliani, Luis M. Robledo
We study the cluster emission properties of 224Ra and 238Pu employing the Barcelona-Catania-Paris-Madrid (BCPM) energy density functional (EDF). Starting from two-dimensional poten…
Multimodal fission from self-consistent calculations
Daniel Lay, Eric Flynn, Sylvester Agbemava +4
When multiple fission modes coexist in a given nucleus, distinct fragment yield distributions appear. Multimodal fission has been observed in a number of fissioning nuclei spanning…
Odd nuclei and quasiparticle excitations within the Barcelona Catania Paris Madrid energy density functional
S. A. Giuliani, L. M. Robledo
An extension of the Barcelona Catania Paris Madrid (BCPM) energy density functional is proposed to deal with odd-mass systems as well as multiquasiparticle excitations. The extensi…
Neural Network Emulation of Spontaneous Fission
Daniel Lay, Eric Flynn, Samuel A. Giuliani +2
Large-scale computations of fission properties are an important ingredient for nuclear reaction network calculations simulating rapid neutron-capture process (the r process) nucleo…
Theoretical description of fission yields: towards a fast and efficient global model
Jhilam Sadhukhan, Samuel A. Giuliani, Witold Nazarewicz
Background: A quantitative microscopic understanding of the fission-fragment yield distributions represents a major challenge for nuclear theory as it involves the intricate compet…
Lightweight self-conjugate nucleus Zr
A. Hamaker, E. Leistenschneider, R. Jain +10
Protons and neutrons in the atomic nucleus move in shells analogous to the electronic shell structures of atoms. Nuclear shell structure varies across the nuclear landscape due to…
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…
Efficient method for estimation of fission fragment yields of r-process nuclei
Jhilam Sadhukhan, Samuel A. Giuliani, Zachary Matheson +1
More than half of all the elements heavier than iron are made by the rapid neutron capture process (or r process). For very neutron-rich astrophysical conditi…
Quantified limits of the nuclear landscape
Léo Neufcourt, Yuchen Cao, Samuel A. Giuliani +3
The chart of the nuclides is limited by particle drip lines beyond which nuclear stability to proton or neutron emission is lost. Predicting the range of particle-bound isotopes po…
Beyond the proton drip line: Bayesian analysis of proton-emitting nuclei
Léo Neufcourt, Yuchen Cao, Samuel Giuliani +3
The limits of the nuclear landscape are determined by nuclear binding energies. Beyond the proton drip lines, where the separation energy becomes negative, there is not enough bind…
Spallation-altered accreted compositions for X-ray bursts: Impact on ignition conditions and burst ashes
J. S. Randhawa, Z. Meisel, S. A. Giuliani +5
Dependable predictions of the X-ray burst ashes and light curves require a stringent constraint on the composition of the accreted material as an input parameter. Lower metallicity…
Fission and the r-process nucleosynthesis of translead nuclei in neutron star mergers
Samuel A. Giuliani, Gabriel Martínez-Pinedo, Meng-Ru Wu +1
We study the impact of fission on the production and destruction of translead nuclei during the r-process nucleosynthesis occurring in neutron-star mergers. Abundance patterns and…

We study the role of dynamic pairing correlations in fission dynamics by considering intrinsic Hartree-Fock-Bogoliubov wave functions that are obtained by minimizing the particle n…
