Ab initio nucleon-nucleus elastic scattering with chiral effective field theory uncertainties
R. B. Baker, B. McClung, Ch. Elster +4
Background: Effective interactions for nucleon-nucleus () elastic scattering from first principles require the use of the same nucleon-nucleon () interaction in the structu…
Ab initio Translationally Invariant Nonlocal One-body Densities from No-core Shell-model Theory
M. Burrows, Ch. Elster, G. Popa +3
[Background:] It is well known that effective nuclear interactions are in general nonlocal. Thus if nuclear densities obtained from {\it ab initio} no-core-shell-model (NCSM) calcu…
Ab initio translationally invariant nucleon-nucleus optical potentials
M. Burrows, K. D. Launey, A. Mercenne +4
We combine the \textit{ab initio} symmetry-adapted no-core shell model (SA-NCSM) with the single-particle Green's function approach to construct optical potentials rooted in first…
Nuclear spin features relevant to ab initio nucleon-nucleus elastic scattering
R. B. Baker, M. Burrows, Ch. Elster +4
Background: Effective interactions for elastic nucleon-nucleus scattering from first principles require the use of the same nucleon-nucleon interaction in the structure and reactio…
Response functions and giant monopole resonances for light to medium-mass nuclei from the \textit{ab initio} symmetry-adapted no-core shell model
M. Burrows, R. B. Baker, S. Bacca +3
Using the \textit{ab initio} symmetry-adapted no-core shell model, we compute sum rules and response functions for light to medium-mass nuclei, starting from interactions that are…
Chiral uncertainties in ab initio nucleon-nucleus elastic scattering
R. B. Baker, M. Burrows, Ch. Elster +4
The effective interaction between a nucleon and a nucleus is one of the most important ingredients for reaction theories. Theoretical formulations were introduced early by Feshbach…
Ab initio Leading Order Effective Potentials for Elastic Nucleon-Nucleus Scattering
M. Burrows, R. B. Baker, Ch. Elster +4
Background: Calculating microscopic effective interactions (optical potentials) for elastic nucleon-nucleus scattering has already in the past led to a large body of work. For firs…
Ab initio Folding Potentials for Nucleon-Nucleus Scattering based on NCSM One-Body Densities
M. Burrows, Ch. Elster, S. P. Weppner +4
Calculating microscopic optical potentials for elastic nucleon-nucleus scattering has already led to large body of work in the past. For folding first-order calculations the nucleo…
Nonlocal structure of the leading order \textit{ab initio} effective potentials for proton elastic scattering from light nuclei
Ch. Elster, M. Burrows, R. B. Baker +4
Based on the spectator expansion of the multiple scattering series we employ a chiral next-to-next-to-leading order (NNLO) nucleon-nucleon interaction on the same footing in the st…
Spin dependent ab initio nonlocal No-Core Shell-Model One-Body Densities
G. Popa, M. Burrows, Ch. Elster +3
Constructing microscopic effective interactions (`optical potentials') for nucleon-nucleus (NA) elastic scattering requires in first order off-shell nucleon-nucleon (NN) scattering…
Ab initio folding potentials for proton-nucleus scattering with NCSM nonlocal one-body densities
Ch. Elster, M. Burrows, S. P. Weppner +3
Based on the spectator expansion of the multiple scattering series we employ a nonlocal translationally invariant nuclear density derived from a chiral next-to-next-to-leading orde…
Nuclear structure and elastic scattering observables obtained consistently with different NN interactions
R. B. Baker, M. Burrows, Ch. Elster +3
Nucleon-nucleon () interactions based on chiral effective theories are commonly used in ab initio calculations of light nuclei. Here we present a study based on three different…
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…
