Radiative strength functions from the energy-localized Brink-Axel hypothesis
Oliver C. Gorton, Konstantinos Kravvaris, Jutta E. Escher +1
Radiative strength functions (RSFs) model the bulk electromagnetic response of highly-excited nuclei and are critical inputs for statistical reaction codes. In this paper, we prese…
Ab initio symmetry-adapted approaches to nuclear reactions
Kristina D Launey, Grigor H. Sargsyan, Alexis Mercenne +2
In this review, we discuss recent applications of the ab initio symmetry-adapted no-core shell-model (SA-NCSM) theory for study and prediction of structure and reactions of stable…
Motivations for Early High-Profile FRIB Experiments
B. Alex Brown, Alexandra Gade, S. Ragnar Stroberg +39
This white paper is the result of a collaboration by those that attended a workshop at the Facility for Rare Isotope Beams (FRIB), organized by the FRIB Theory Alliance (FRIB-TA),…
Ab initio informed 20Ne(p, p)16O reaction elucidates the emergence of alpha clustering from chiral potentials
G. H. Sargsyan, Kazuki Yoshida, Kazuyuki Ogata +4
We report on the first \textit{ab initio} informed knock-out reaction in the intermediate-mass region, with the aim to probe the underlying chiral potential and its impact on t…
Towards next-generation optical potentials for nuclear reactions and structure calculations
Salvatore Simone Perrotta, Cole Davis Pruitt, Oliver C. Gorton +1
Optical-model potentials (OMPs) are critical ingredients for basic and applied nuclear physics. Present-day computational capabilities allow us to generate data-driven nucleon-nucl…
Microscopic optical potentials from a Greens function approach
G. H. Sargsyan, G. Potel, K. Kravvaris +1
Optical potentials are a standard tool in the study of nuclear reactions, as they describe the interaction between a target nucleus and a projectile. The use of phenomenological op…
Correcting for neutron width fluctuations in Hauser-Feshbach gamma branching ratios
Oliver C. Gorton, Jutta E. Escher
Porter-Thomas fluctuations of neutron widths skew compound nuclear decay probabilities from their statistical Hauser-Feshbach values. We present a straightforward method to correct…
Optical potentials for the rare-isotope beam era
C. Hebborn, F. M. Nunes, G. Potel +26
We review recent progress and motivate the need for further developments in nuclear optical potentials that are widely used in the theoretical analysis of nucleon elastic scatterin…
Toward a complete theory for predicting inclusive deuteron breakup away from stability
G. Potel, G. Perdikakis, B. V. Carlson +12
We present an account of the current status of the theoretical treatment of inclusive reactions in the breakup-fusion formalism, pointing to some applications and making th…
Separable Potentials for (d,p) Reaction Calculations
Ch. Elster, L. Hlophe, V. Eremenko +4
An important ingredient for applications of nuclear physics to e.g. astrophysics or nuclear energy are the cross sections for reactions of neutrons with rare isotopes. Since direct…
Separable Forces for Reactions in Momentum Space
L. Hlophe, Ch. Elster, V. Eremenko +4
Treating reactions in a Faddeev-AGS framework requires the interactions in the sub-systems as input. We derived separable representations for the neutron- and proton-nucleu…
Towards a Faddeev-AGS description of reactions with heavy nuclei: Regularizing integrals with Coulomb functions
The TORUS Collaboration, V. Eremenko, L. Hlophe +5
The repulsive Coulomb force poses severe challenges when describing reactions for highly charged nuclei as a three-body problem. Casting Faddeev-AGS equations in a Coulomb…
