Direct transfer to K46,48 as a survey of the π(s1/2)−ν(sdpf) interaction

C. J. Paxman et al.

Phys. Rev. C 114, 044318 (2026) - Published 15 October, 2026

Nucleon-adding and -removing transfer reactions provide a unique experimental window into the anatomy of the shell-model picture of atomic nuclei. The authors put the neutron-removing transfer reaction 47K(d,t) and the neutron-adding counterpart 47K(d,p) to work for meticulously probing our understanding of the neutron shell structure and interaction of the last valence proton in 46K. With that, they provided a unique benchmark for the nuclear shell model on the quest to describe shell evolution in neutron-rich nuclei.

Nonlocal nucleon-nucleus optical potentials from chiral effective field theory

L. M. Stahulak and J. W. Holt

Phys. Rev. C 114, 044324 (2026) - Published 20 October, 2026

Optical potentials model scattering off complex nuclear targets, but are typically phenomenological in nature. Here a widely used parameterization for nonlocal potentials, the Perey-Buck ansatz, is linked with calculations using first-principles forces. This provides insight into the success of Perey-Buck, as well as important lessons on its limitations.

Neutron fluence and relation of yields for transuranium nuclei during nucleosynthesis under conditions of thermonuclear explosions

V. I. Lyashuk

Phys. Rev. C 114, 044603 (2026) - Published 1 October, 2026

There is much interest and activity in identifying transuranium isotopes and determining their cosmological origins, such as neutron star mergers. This paper studies how one could determine the production of transuranium isotopes in pulse nucleosynthesis based on isotopic yield ratios, a process that is very dependent on neutron fluence. The relationship between the neutron flux and abundances is determined in a rather unique way: by looking at yields from nuclear tests conducted during the Plowshares program. Making use of these nuclear tests (indicated in the figure) may help determine whether the periodic table has been extended in natural events in space.

Ab initio study of Li7 with coupled mass partitions

Jakub Herko, Konstantinos Kravvaris, Sofia Quaglioni, Petr Navrátil, Guillaume Hupin, and Mark A. Caprio

Phys. Rev. C 114, 044613 (2026) - Published 13 October, 2026

A new capability of describing charge-exchange and transfer reactions by coupling different mass/charge partitions of the compound nucleus was developed within ab initio nuclear theory. We apply this capability to 7Li, employing the no-core shell model with continuum for the first time in a calculation that couples three mass/charge partitions, namely 4He + 3H, 6Li + n, and 6He + p, using a chiral nucleon-nucleon interaction as input. Specifically, we investigate the effect of interpartition coupling on the spectrum of 7Li and calculate cross sections for the 6Li(n,p)6He, 6He(p,n)6Li, and 6He(p,t)4He reactions. The results show that coupling the relevant mass/charge partitions is important for a consistent description of the 7Li spectrum and reaction cross sections, and offers a useful framework for interpreting existing data and guiding future measurements. This work also paves the way for calculations of transfer reactions relevant for fusion energy generation such as 6Li(n,t)4He.

Comparative study of Langevin and random walk models for nuclear fission in the overdamped regime

A. Augustyn, T. Cap, M. Kowal, and K. Pomorski

Phys. Rev. C 114, 044614 (2026) - Published 13 October, 2026

Fission is a highly dissipative process. Stochastic methods like Brownian shape motion and Langevin dynamics couple macroscopic-microscopic models with dynamics. This paper compares and contrasts these two approaches within a consistent framework and demonstrates the connections between them. The work also hints at the potential role of higher-dimensional deformation modes in broadening the widths of the fission fragment mass yields to better match the measured yields.

Quarkyonic quark-meson coupling model for nuclear and neutron matter

Koichi Saito, Tsuyoshi Miyatsu, and Myung-Ki Cheoun

Phys. Rev. C 114, 045201 (2026) - Published 1 October, 2026

We have constructed a quark-based nuclear model that extends from low densities into the crossover region where nucleonic matter begins to evolve into quark matter. It combines the quark-meson coupling model with the dual quarkyonic picture. A relativistic treatment of quark wave functions within nucleons ensures that quarkyonic matter emerges above nuclear saturation density, preserving consistency with conventional low-energy nuclear physics. Nuclear interactions are crucial for quantitative predictions in the quarkyonic regime. The predicted sound speed exhibits a pronounced peak and is consistent with constraints inferred from neutron-star observations using neural networks and Bayesian inference. The calculated pressures in symmetric nuclear matter and pure neutron matter also lie within the ranges inferred from high-energy heavy-ion collisions. This framework can help address the hyperon puzzle in massive neutron stars.

Measurement of the Gerasimov-Drell-Hearn integrand for the proton and deuteron from 200 to 1400 MeV

P. Pedroni et al. (A2 Collaboration at MAMI)

Phys. Rev. C 114, 045203 (2026) - Published 1 October, 2026

The Gerasimov-Drell-Hearn (GDH) sum rule establishes a fundamental link between the total absorption cross section of circularly polarized photons on longitudinally polarized nucleons and nuclei and their static properties. The two relative spin configurations, parallel or antiparallel, determine the absorption cross sections, σP and σA. The sum rule relates the difference of the cross sections (Δσ) to the mass, spin, and anomalous magnetic moment of the nucleon (nucleus). It implies that a non-zero anomalous magnetic moment is connected to the excitation spectrum of the nucleon (nucleus) and, therefore, to its composite nature. Thus, measuring the GDH sum rule integral for different nuclear targets is a sensitive tool for studying both the nucleon resonance properties and the modifications of nucleon properties inside the nuclear medium. We present new precise data on the helicity-dependent total inclusive photoabsorption cross section for the proton and the deuteron, verifying the validity of the GDH sum rule. These new data provide a precise experimental benchmark for theoretical models of nucleons, both free and embedded in the nuclear medium.

Measurement of the neutron incoherent scattering length of Hg199 using stored ultracold neutrons

C. Abel et al. (nEDM Collaboration)

Phys. Rev. C 114, 045501 (2026) - Published 1 October, 2026

The imbalance between matter and antimatter in our Universe remains one of the great mysteries of modern physics. The neutron’s electric dipole moment (EDM) is a sensitive probe of new sources of CP violation that could help explain this asymmetry. Searches for an EDM rely on extraordinarily precise measurements of the neutron spin precession, using polarized mercury atoms to monitor the applied magnetic field. But the mercury atoms themselves can interact with neutrons in a way that produces a tiny, spin-dependent frequency shift, potentially mimicking an EDM signal. In this study, the nEDM Collaboration, with the experiment based at the Paul Scherrer Institute, directly investigates this subtle neutron-mercury interaction. The results provide a precise characterization of an important systematic effect, improving the control of a key source of uncertainty in EDM measurements.

Quarkyonic quark-meson coupling model for nuclear and neutron matter

Koichi Saito, Tsuyoshi Miyatsu, and Myung-Ki Cheoun

Phys. Rev. C 114, 045201 (2026) - Published 1 October, 2026

We have constructed a quark-based nuclear model that extends from low densities into the crossover region where nucleonic matter begins to evolve into quark matter. It combines the quark-meson coupling model with the dual quarkyonic picture. A relativistic treatment of quark wave functions within nucleons ensures that quarkyonic matter emerges above nuclear saturation density, preserving consistency with conventional low-energy nuclear physics. Nuclear interactions are crucial for quantitative predictions in the quarkyonic regime. The predicted sound speed exhibits a pronounced peak and is consistent with constraints inferred from neutron-star observations using neural networks and Bayesian inference. The calculated pressures in symmetric nuclear matter and pure neutron matter also lie within the ranges inferred from high-energy heavy-ion collisions. This framework can help address the hyperon puzzle in massive neutron stars.

The Gerasimov-Drell-Hearn (GDH) sum rule establishes a fundamental link between the total absorption cross section of circularly polarized photons on longitudinally polarized nucleons and nuclei and their static properties. The two relative spin configurations, parallel or antiparallel, determine the absorption cross sections, σP and σA. The sum rule relates the difference of the cross sections (Δσ) to the mass, spin, and anomalous magnetic moment of the nucleon (nucleus). It implies that a non-zero anomalous magnetic moment is connected to the excitation spectrum of the nucleon (nucleus) and, therefore, to its composite nature. Thus, measuring the GDH sum rule integral for different nuclear targets is a sensitive tool for studying both the nucleon resonance properties and the modifications of nucleon properties inside the nuclear medium. We present new precise data on the helicity-dependent total inclusive photoabsorption cross section for the proton and the deuteron, verifying the validity of the GDH sum rule. These new data provide a precise experimental benchmark for theoretical models of nucleons, both free and embedded in the nuclear medium.

The imbalance between matter and antimatter in our Universe remains one of the great mysteries of modern physics. The neutron’s electric dipole moment (EDM) is a sensitive probe of new sources of CP violation that could help explain this asymmetry. Searches for an EDM rely on extraordinarily precise measurements of the neutron spin precession, using polarized mercury atoms to monitor the applied magnetic field. But the mercury atoms themselves can interact with neutrons in a way that produces a tiny, spin-dependent frequency shift, potentially mimicking an EDM signal. In this study, the nEDM Collaboration, with the experiment based at the Paul Scherrer Institute, directly investigates this subtle neutron-mercury interaction. The results provide a precise characterization of an important systematic effect, improving the control of a key source of uncertainty in EDM measurements.
