Ab initio predictions link the neutron skin of 208Pb to nuclear forces

Baishan Hu et al.

Summary: The study investigates the influence of nuclear forces on heavy atomic nuclei and provides insights into predicting nuclear properties and neutron stars. By utilizing advanced methods and techniques, researchers can quantitatively predict the properties of Pb-208 and obtain relatively accurate results. The findings demonstrate the importance of realistic forces in heavy atomic nuclei and enable quantitative predictions across the nuclear landscape.

Isospin symmetry breaking in the charge radius difference of mirror nuclei

Tomoya Naito et al.

Summary: The effects of isospin symmetry breaking on the charge radius difference of mirror nuclei were studied in this research. The study focused on the examples of 48Ca and 48Ni, where certain effects could be neglected for a transparent analysis. It was found that isospin symmetry breaking effects can significantly impact the estimated value for the symmetry energy slope parameter. However, recent ab initio calculations suggest that the effects on ground-state energy and charge radii might be relatively small.

Fast emulation of quantum three-body scattering

Xilin Zhang et al.

Summary: The researchers developed emulators for solving quantum three-body scattering problems using a combination of variational method and eigenvector continuation concept. The emulators were shown to be accurate and efficient through a nuclear-physics model, and the researchers argued that this strategy could be applied to other fields as well.

Information content of the differences in the charge radii of mirror nuclei

Paul-Gerhard Reinhard et al.

Summary: Differences in charge radii of mirror nuclei are suggested to contain information on the slope of the symmetry energy. However, statistical correlation analysis shows that the difference in charge radii, Delta R-ch(mir), is an inferior indicator compared to other observables such as neutron skin or electric dipole polarizability. The presence of pairing correlations and low-lying proton continuum affects Delta R-ch(mir). Therefore, the precise data on mirror charge radii cannot provide a stringent constraint on the slope of the symmetry energy L.

Toward ab initio charge symmetry breaking in nuclear energy density functionals

Tomoya Naito et al.

Summary: This article proposes a new approach to determine the strength of the charge symmetry breaking term in nuclear density functional theory. It shows that by using the mass difference of mirror nuclei and the neutron-skin thickness of doubly-closed-shell nuclei, the strength of the CSB interaction can be constrained separately from other isospin symmetry breaking forces with an uncertainty of less than 6%.

Fast & accurate emulation of two-body scattering observables without wave functions

J. A. Melendez et al.

Summary: The article presents a fast and accurate emulator for two-body scattering observables, which combines Newton's variational method with ideas from eigenvector continuation. The emulator is shown to accurately extrapolate far from the support of the training data, providing significant improvement in CPU time when used to emulate interactions with multiple free parameters.

Charge radii of exotic potassium isotopes challenge nuclear theory and the magic character of N=32

A. Koszorus et al.

Summary: Nuclear charge radii serve as sensitive probes of the nucleon-nucleon interaction and nuclear matter properties, posing a challenge for nuclear theory. Experimental evidence suggests a new magic neutron number at N=32 in the calcium region, with unexpectedly large increases in charge radii raising questions about nuclear size evolution in neutron-rich systems. Advanced nuclear theories offer different explanations for the odd-even variations and notable increase in charge radii beyond N=28, highlighting limitations in our understanding of neutron-rich systems and issues in current nuclear theory models.

Precision Determination of Pion-Nucleon Coupling Constants Using Effective Field Theory

P. Reinert et al.

Summary: The pion-nucleon coupling constants are fundamental observables that determine the strength of long-range nuclear forces and play a crucial role in nuclear physics research. Precision determination of these constants using chiral effective field theory and Bayesian methodology shows accurate values at the percent level with no significant charge dependence, marking an important step towards developing a precise theory of nuclear forces and structure.

Rigorous constraints on three-nucleon forces in chiral effective field theory from fast and accurate calculations of few-body observables

S. Wesolowski et al.

Summary: This study explores the constraints on the three-nucleon force (3NF) of chiral effective field theory (xEFT) by incorporating experimental error, computational method uncertainty, and the uncertainty due to truncation of the xEFT expansion at next-to-next-to-leading order. Including xEFT truncation errors in the analysis is crucial for obtaining a consistent solution for the binding energy and decay rate of certain nuclear states. The findings suggest an xEFT expansion parameter of Q = 0.33 +/- 0.06 for the observed nuclear properties.

Neutron-neutron scattering length from the 6He(p, pα)nn reaction

Matthias Goebel et al.

Summary: A novel method using the He-6(p, p alpha)nn reaction was proposed to measure the neutron-neutron scattering length. The method is based on final-state interaction between neutrons after the knockout of the alpha particle. The neutron-neutron relative-energy distribution details allow for a precise extraction of the s-wave scattering length.
