Magnetic dipole γ-ray strength functions in the crossover from spherical to deformed neodymium isotopes

A. Mercenne, P. Fanto, W. Ryssens, and Y. Alhassid

Phys. Rev. C 110, 054313 (2024) - Published 13 November, 2024

The γ-ray strength function is an important input into Hauser-Feshbach calculations of neutron capture in compound nuclear reactions. Experiments suggest an enhancement of the strength function at low energy, but this enhancement has not been reproduced in models of heavy nuclei as conventional shell-model methods become computationally intractable. Using shell-model Monte Carlo methods, the authors have successfully reproduced the low-energy enhancement (LEE) for magnetic dipole transitions in neodymium isotopes, while also illuminating the role of the scissors and spin-flip modes in these M1 transitions. If the LEE persists in heavy neutron-rich nuclei, thus significantly enhancing the radiative neutron-capture rates of nuclei near the neutron drip line, it would likely have profound effects on r-process nucleosynthesis.

Radial and orbital decomposition of charge radii of Ca nuclei: Comparative study of Skyrme and Fayans functionals

T. Inakura, N. Hinohara, and H. Nakada

Phys. Rev. C 110, 054315 (2024) - Published 14 November, 2024

Accurate computation of nuclear radii is surprisingly challenging. By decomposing the contributions into orbital occupations and radial wave functions, the authors tease out a sensitive dependence upon the details of the pairing force, providing an improved description of the radii of stable calcium isotopes. Measurements of the radii of neutron-deficient calcium isotopes would help further constrain these insights.

Magnetic structure of A10 nuclei using the Norfolk nuclear models with quantum Monte Carlo methods

G. Chambers-Wall, A. Gnech, G. B. King, S. Pastore, M. Piarulli, R. Schiavilla, and R. B. Wiringa

Phys. Rev. C 110, 054316 (2024) - Published 18 November, 2024

This paper presents a new detailed study of magnetic moments and form factors of nuclei with mass number A up to 10, based on ab-initio approaches and chiral effective field theory. The results of quantum Monte Carlo calculations for elastic magnetic form factors show excellent agreement with experimental data out to momentum transfers q3 fm1. Benchmarking such electroweak current models against available data over a wide range of kinematics allows for accurate predictions, which are very important to disentangle signals of new physics from nuclear physics effects.

Diagrammatic ab initio methods for infinite nuclear matter with modern chiral interactions

F. Marino, W. G. Jiang, and S. J. Novario

Phys. Rev. C 110, 054322 (2024) - Published 22 November, 2024

A realistic description of the equation of state of nuclear matter is of paramount importance for understanding neutron-star structure and astrophysical phenomena. The authors perform benchmark ab initio calculations for nuclear matter with several modern chiral interactions using three diagrammatic methods: coupled-cluster theory, self-consistent Green’s functions, and many-body perturbation theory. They obtain robust predictions for the equation of state of both pure neutron matter and symmetric nuclear matter, especially for soft chiral potentials. The very good agreement between different techniques, in particular between the nonperturbative coupled-cluster and Green’s functions methods, suggests that these many-body approaches can reach high accuracy, and uncertainties on the equation of state are mostly related to the nuclear interaction.

Role of momentum in the generator-coordinate method applied to barrier penetration

K. Hagino and G. F. Bertsch

Phys. Rev. C 110, 054610 (2024) - Published 18 November, 2024

This manuscript introduces a fresh theory perspective on nuclear fission. The typical approach to fission uses collective coordinates with, e.g., the potential energy derived from semiclassical microscopic-macroscopic models or from density functional theories. The novel approach is based on the configuration-interaction framework, which has been successful for calculating energies and spectroscopic properties, along with the generator-coordinate method introduced by Hill and Wheeler. Here the total wavefunction is represented by a superposition of Slater determinants characterized by the collective coordinate along the fission path. As an important new step, configurations with finite momenta are taken into account. With Kohn’s reaction theory to treat barrier penetration assuming a Gaussian-shaped barrier, the authors show that including the finite momentum configurations leads to a more stable and more accurate solution. This method, while applied to fission here, could be useful for other systems involving interacting fermions.

Bayesian analysis of (3+1)D relativistic nuclear dynamics with the RHIC beam energy scan data

Syed Afrid Jahan, Hendrik Roch, and Chun Shen

Phys. Rev. C 110, 054905 (2024) - Published 13 November, 2024

The state-of-the-art in the modeling and analysis of relativistic heavy-ion collisions involves multistage approaches to simulate the evolving strongly interacting matter and uses Bayesian analysis to obtain statistically relevant physical quantities. This work features a (3+1)D model applied to collision energies lower than those considered so far to explore the full range of the RHIC beam energy scan. This enables an exploration of the behavior of QCD at large baryon chemical potentials. The results of such comprehensive and systematic phenomenological studies have promise to advance knowledge of QCD in extreme conditions.

Vortex rings in event-by-event relativistic heavy-ion collisions

David Dobrigkeit Chinellato, Michael Annan Lisa, Willian Matioli Serenone, Chun Shen, Jun Takahashi, and Giorgio Torrieri

Phys. Rev. C 110, 054908 (2024) - Published 15 November, 2024

Vortices such as smoke rings in air are familiar features in hydrodynamics. They appear when fast-moving local currents are embedded in the larger medium. This paper reports on results of realistic simulations of relativistic heavy-ion collisions using relativistic fluid dynamics. The work highlights the formation of a novel toroidal vortex ring structure which could manifest itself in the polarization of the Λ hyperon. This proposed new observable is argued to have great potential as a probe of hydrodynamic behavior in small collision systems, and of early-time dynamics in general. The predictions made in this work can be tested by experiments performed at current heavy-ion colliders such as RHIC at BNL and the LHC at CERN, as well as by future fixed-target experiments to be carried out at the LHC.

Ab initio electroweak corrections to superallowed β decays and their impact on Vud

Vincenzo Cirigliano, Wouter Dekens, Jordy de Vries, Stefano Gandolfi, Martin Hoferichter, and Emanuele Mereghetti

Phys. Rev. C 110, 055502 (2024) - Published 18 November, 2024

The authors propose a new approach for the calculation of nuclear-dependent corrections to superallowed β decays based on effective field theory (EFT). The calculation is timely given the observation in recent years of a 2–3 σ anomaly in the test of the first row of the Cabibbo-Kobayashi-Maskawa matrix. Within a comprehensive assessment, the authors methodically develop a master formula for superallowed β decays, paving the way for ab-initio nuclear many-body computations of nuclear-structure-dependent corrections. The results show promise for state-of-the-art extractions of Vud from nuclear processes with controlled uncertainty quantification, and for using precision β-decay experiments to search for physics beyond the standard model.

Laser-based approach to verify nuclear excitation by electron capture

Jintao Qi, Boqun Liu, and Xu Wang

Phys. Rev. C 110, L051601 (2024) - Published 12 November, 2024

When the conditions are right, the energy released in a downward electronic transition in an atom can excite its atomic nucleus, potentially creating a path to controlling excited nuclear quantum states. Among these processes, nuclear excitation by electron capture (NEEC) stands out as the only one that has not yet been unambiguously confirmed by experiment, despite theoretical proposals spanning nearly half a century. The authors propose using intense femtosecond laser pulses on clusters of 235U atoms, demonstrating that with suitable laser parameters, the 76.7-eV nuclear isomer in 235U is almost entirely (more than 99.9%) excited via NEEC. The long, 26-minute lifetime of the isomer allows for efficient detection and diminishes atomic processes disturbing the detection. An experimental confirmation would represent a robust and conclusive verification of this elusive phenomenon.

The authors propose a new approach for the calculation of nuclear-dependent corrections to superallowed β decays based on effective field theory (EFT). The calculation is timely given the observation in recent years of a 2–3 σ anomaly in the test of the first row of the Cabibbo-Kobayashi-Maskawa matrix. Within a comprehensive assessment, the authors methodically develop a master formula for superallowed β decays, paving the way for ab-initio nuclear many-body computations of nuclear-structure-dependent corrections. The results show promise for state-of-the-art extractions of Vud from nuclear processes with controlled uncertainty quantification, and for using precision β-decay experiments to search for physics beyond the standard model.
