        <description><![CDATA[Precision tests of the Standard Model using β decay have always relied on a careful choice of transition to minimize residual nuclear structure uncertainties. Following breakthroughs in nucleon-level radiative corrections in the last decade, however, corrections due to nuclear structure are once more a limiting factor in several scenarios. Progress in ab initio nuclear theory provides a path forward, but common recoil-order approximations in traditional formalisms often go unnoticed. Here, we critically examine their origin and address recently resolved issues as well as identify open questions.]]></description>

        <description><![CDATA[The era of precision ab initio nuclear theory has arrived, enabling uncertainty-quantified predictions for nuclear structure and for interactions with external probes directly from the underlying nuclear force and electroweak currents. This review highlights recent breakthroughs that extend ab initio calculations to the heavy nucleus 208Pb, to medium-mass systems with complex deformation, and to weakly-bound nuclei near the driplines. We also summarize ab initio calculations of nuclear responses for dark matter direct detection. Together, these advances demonstrate how ab initio methods can substantially reduce nuclear-physics uncertainties in searches for physics beyond the Standard Model, providing a more robust interpretation of current and forthcoming precision experiments.]]></description>

        <description><![CDATA[An ongoing experimental campaign at the National Ignition Facility (NIF) aims to measure neutron induced nuclear reaction cross–sections using radiochemically doped target capsules. Critical to this campaign is the ability to collect a representative sample of the reaction products using Solid Radiochemical Collectors (SRCs) fielded around the NIF chamber. The shot presented in this paper used a doped target capsule with a neopentane gas fill was to investigate the ratio of isotopes collected at three chamber angles. It was found that SRC samples of rare earth elements collected from NIF are representative of the ingoing dopant mix, thereby concluding that fractionation does not occur during a NIF implosion. This validates the doped capsule method for use in measuring neutron induced reaction cross-sections.]]></description>

        <description><![CDATA[Magic numbers are the backbone of the nuclear structure, serving as the basis for shell-model truncations, leading to the prediction of the island of stability, and linking to peaks in the solar-system abundance curve. Canonical nuclear magic numbers include 2, 8, 20, 28, 50, 82, and 126. It is now well established that these magic numbers are not universal over the nuclear landscape. This paper presents a brief review of recent highlights on the migration of magic numbers in neutron-rich nuclei, with particular emphasis on results obtained from knockout reactions. We focus on two key regions: 1) the loss of magicity at N = 20 and 28, and 2) the emergence of new magic numbers at N = 32, 34. Prospects for future measurements in these regions, enabled by new detection systems at upgraded and new facilities, are also discussed.]]></description>

        <description><![CDATA[An optical model analysis is performed for deuteron-induced elastic scattering on light nuclei from 3He to 16O over an extended energy range from 10 to 270 MeV. The aim of this study is to perform systematic local optical-model analysis of differential elastic scattering data and to compare the results with those obtained from widely used global parameterizations. Experimental angular distributions are extracted from the EXFOR database and analyzed within a Woods-Saxon potential framework, with particular attention given to the systematic behavior of optical-model parameters for different target masses and energies. Absorption mechanisms have been studied varying the role of surface and volume components in the imaginary potential. A spin–orbit term was included in the calculations using standard fixed parameters in order to maintain consistency with conventional optical-model descriptions; however, no attempt was made to extract systematics of the spin–orbit interaction due to the limited sensitivity of elastic scattering data without polarization observables, revealing a systematic transition from surface-dominated absorption in light and cluster-like nuclei—driven by deuteron breakup—to increasingly volume-dominated absorption for heavier systems. Volume integrals of both the volume and surface imaginary components, together with reaction cross sections, were calculated to assess the consistency and stability of the fitted potentials and to examine systematic trends. Comparisons to global optical-model potentials show that global models give a reasonable reproduction of the average behavior at forward angles, but often deviate at intermediate and backward angles, with the local fits generally providing better agreement with the angular distributions. These results underline the importance of localized analyses for deuteron elastic scattering on light nuclei and allow for a quantitative and systematic assessment of the applicability of global optical potentials in this mass region.]]></description>

        <description><![CDATA[The vibron model classifies energy spectra through U(n)→ SO(n) irreducible representation (irrep) branching, enabling exploration of quantum phase transitions between vibrational and rotational regimes. We advance a solvable Bethe Ansatz framework, deriving exact solutions for the vibron Hamiltonian and addressing discrepancies in prior studies. By applying algebraic techniques, we demonstrate that precise control parameters—rather than q-deformation—are essential for accurate spectral predictions. This study critically reassesses existing computational methods, emphasizing parameter optimization to improve alignment with experimental data. Our refined approach accurately reproduces the procedure for obtaining reproducible molecular energy spectra, elucidating the impact of control parameters on quantum phase transitions.]]></description>

        <description><![CDATA[The total cross-section of the radiative neutron capture reaction 14С(n,γ0+1)15C—for energies ranging from 10 meV to 5 MeV—is considered. Calculations performed in the framework of the modified potential cluster model with forbidden states show an agreement of total cross-section σ (23.3 keV) = 4.75 μb with the presently recommended value 4.86(48) μb by Ma et al., 2020. The efficiency of carbon isotope 15C production is illustrated by the 14С(n,γ0+1)15C reaction rate calculated at temperatures from T9 = 0.001 to T9 = 10. The conventional Maxwell–Boltzmann weighted reaction rate σvMB of the present work is comparable, with less than 10% accuracy, with the latest calculations by Ma et al., 2020 and Bhattacharyya et al., 2021. The estimation of non-extensive effects is implemented using our data on the reaction rate σvMB as reference values. The efficiency of carbon isotope production in radiative capture reactions 12-14С(n,γ)13-15C is estimated based on the calculated reaction rates. The influence of the Maxwellian-weighted 12-14C(n,γ)13-15C reaction rates on the ratios 12C/13C and 13C/14C is examined. Tsallis statistics is applied for the first time to the calculation of the 14С(n,γ0)15C reaction rate with values of non-extensive parameter 0.7 ≤ q ≤ 1.3 on the background of Maxwell–Boltzmann statistics corresponding to q = 1. The reaction rate σvq shows a factor ∼4 increase for q = 0.7 and a factor ∼0.6 decrease for q = 1.3 compared to q = 1.]]></description>

        <description><![CDATA[We report atomic mass measurements of the unstable nuclides 73−75Ni, 73−78Cu, and 74−78Zn, which have been accomplished using multi-reflection time-of-flight mass spectrometry combined with new technical developments to resolve challenges for exotic-isotope identification and selection. The isotopes were produced in-flight at the RIKEN’s Radioactive Ion Beam Facility and delivered to the combined gas cell and multi-reflection system installed downstream of the ZeroDegree spectrometer. The incoming high-energy beam was energy-degraded and subsequently stopped in a helium gas cell. The energy degrader thickness was optimized using a new method that employs signals from plastic scintillators located upstream and downstream of the helium-filled gas cell. Extracted isotopes of interest were mass-selected by the in-MRTOF deflector method, for which we discuss simultaneous selection of multiple isobar chains. The ions of interest were identified unambiguously using β-decay-correlated mass measurements for the first time, which is demonstrated for 78Zn. The new mass values are compared with literature values and recent measurements performed at JYFLTRAP and ISOLTRAP, where a generally good agreement is observed.]]></description>

        <description><![CDATA[In the framework of the multi-source thermal model employing the Tsallis distribution, the transverse momentum distributions of kaon, pion, and (anti-)proton production in U + U collisions at sNN = 193 GeV with varying centrality are investigated. The transverse momentum spectra are appropriately characterized. The dependencies of parameters (average transverse momenta, effective temperature, and entropy index) on event centrality are determined. It is observed that the q parameters increase as the average number of particles participating in the collisions rises, which implies that the nuclear stopping degree elevates with the increase of collision centrality. The T value remains fundamentally consistent for the same particle under different collision parameters, suggesting that the kinetic freezing temperature of particle ejection in this collision system is independent of the collision parameters. However, the q value exceeded the previously determined research range, which might be related to the deformation of the U-nucleus.]]></description>

        <description><![CDATA[We review the experimental knowledge on the dipole polarizability (DP) of nuclei and its relation to the neutron skin thickness and properties of the neutron-rich matter equation of state (EOS). The discussion focuses on recent experiments using relativistic Coulomb excitation in inelastic proton scattering at extreme forward angles covering a mass range from 40Ca to 208Pb. Constraints on the neutron skins and the density dependence of the symmetry energy are derived from a systematic comparison to calculations based on density functional theory (DFT) and ab initio methods utilizing interactions derived from chiral effective field theory (χEFT). The results consistently favor a soft EOS around or slightly below the saturation point. An outlook is provided on possible improvements in the precision achievable in stable nuclei and studies of exotic neutron-rich unstable nuclei with upcoming experimental facilities.]]></description>

        <description><![CDATA[Understanding the nucleosynthesis and energy generation in quiescent and explosive stellar burning requires a detailed understanding of reaction rates on many unstable nuclides. Such reaction rates are often governed by the properties of low-lying, isolated proton resonances. Though direct measurements of resonance strengths are ultimately desired, and are a focus of rare isotope beam facilities worldwide, such tour-de-force experiments must be guided by indirect techniques, in order to know resonance energies, Jπ assignments, and estimated widths, to inform targeted measurements. Furthermore, some important low-lying resonances may be too weak for direct measurements with radioactive beams, and indirect techniques provide the only practical constraints. Additionally, there has been growing interest in the astrophysical role of isomeric states, which can influence the reaction flow in nucleosynthetic reaction networks, and hence impact the quantitative interpretation of astronomical observables, such as γ-ray signatures, and elemental and isotopic ratios. Properties of single-proton resonances can be obtained by exploiting the selectivity of direct reactions, such as single-nucleon transfer and charge-exchange reactions. Constraining proton-capture rates via direct reactions has been a focus of the astrophysics program at ORNL for over two decades, spurring the development of the ORRUBA and GODDESS detector systems. Herein, a review of recent developments in instrumentation and radioactive beam delivery (including isomeric beam experiments) is presented, along with some specific examples of astrophysically interesting sd-shell nuclides, which have been a target of recent ORRUBA and GODDESS experiments.]]></description>

        <description><![CDATA[A systematic study of parametric uncertainties in transfer reactions is performed using the recently developed uncertainty quantified global optical potential (KDUQ). We consider reactions on the doubly-magic spherical nucleus 48Ca and explore the dependence of the predicted (d,p) angular distribution uncertainties at different beam energies and for different properties of the final single-particle state populated by the reaction. Our results show that correlations between the uncertainties associated with the bound state potential and with the optical potentials may be important for correctly determining the uncertainty in the transfer cross sections (in our case, these do not add in quadrature). In general, we find small uncertainties in the predicted transfer observables: half-width of the 68% credible interval is roughly 5−10%, which is comparable to the experimental error on the transfer data. Finally, our results show that the relative magnitude of the parametric uncertainty in transfer observables increases with the beam energy and does not depend strongly on the properties of the final state.]]></description>

        <description><![CDATA[With the combination of nuclear interactions from chiral effective field theory and various many-body techniques, one can perform systematically improvable ab initio calculations. As the improvable framework enables us to quantify the uncertainty, it is particularly useful to make a prediction for which performing experiments is difficult or even impossible. Neutron skin thickness, the difference between neutron and proton distribution radii, is a key quantity related to the properties of infinite nuclear matter. Since neutrons do not have a net electric charge, the neutron-distribution radius is difficult to measure, preventing precise measurement of neutron skin thickness. On the other hand, recent developments in laser spectroscopy techniques can provide detailed information on the charge distribution and opportunities for detailed comparisons to theoretical results. Testing the theoretical frameworks with the measurable charge radii should be a step toward predicting other quantities, such as neutron skin thickness. This contribution reviews recent advances in nuclear radii and neutron skin from ab initio calculations.]]></description>

        <description><![CDATA[IntroductionDirect reactions are crucial tools for accessing properties of the atomic nucleus. Fundamental and exotic phenomena such as collective modes, pairing, weakbinding effects and evolution of single-particles energies can be investigated in peripheral collisions between a heavy nucleus and a light target. The necessity of using inverse kinematics to reveal how these structural properties change with isospin imbalance renders direct reactions a challenging technique when using the missing mass method.MethodsIn this scenario, Active Target Time Projection Chambers (AT-TPC) have demonstrated an outstanding performance in enabling these types of reactions even under conditions of very low beam intensities. The AT-TPC of the Facility for Rare Isotope Beams (FRIB) is a next generation multipurpose Active Target. When operated inside a solenoidal magnet, direct reactions benefit from the measurement of the magnetic rigidity that enables particle identification and the determination of the excitation energy with high resolution without the need of auxiliary detectors. Additionally, the AT-TPC can be coupled to a magnetic spectrometer improving even further its spectroscopic investigation capability.ResultsIn this contribution, we discuss inelastic scattering and transfer reaction data obtained via the AT-TPC and compare them to theory. In particular, we present the results for the 14C(p,p′) and 12Be (p,d)11Be reactions.DiscussionFor 14C, we compare the experimental excitation energy of the first 1– excited state with coupled-cluster calculationsbased on nuclear interactions from chiral effective field theory and with available shell-model predictions. For 12Be, we determine the theoretical spectroscopic factors of the 12Be (p,d)11Be transfer reaction in the shell modeland compare them to the experimental excitation spectrum from a qualitative standpoint.]]></description>

        <description><![CDATA[In this article, we discuss some aspects of the quenching of the single-particle strength with emphasis on the isospin dependence of long- and short-range correlations. A phenomenological analysis that connects recent Jefferson Laboratory studies with data on spectroscopic factors, is contrasted with the results of the Dispersive Optical Model approach. We consider some consequences of the model on the nature of the dressed nucleons in the nuclear medium, their effective masses, as well as other aspects of nuclear structure such as charge radii, effective charges, and spin-spin correlations. Qualitative estimates indicate that short-range correlations must play a significant role on those aspects. Despite the fact that our conclusions are perhaps speculative at this stage, we trust that the results will stimulate further experimental and theoretical work, specifically on exotic nuclei far from stability.]]></description>

        <description><![CDATA[The nuclear ground state properties of 63Co and 63Ni nuclei have been investigated within the framework of the relativistic mean field (RMF) approach. The RMF model with density-dependent meson-exchange (DD-ME2) interaction is used to calculate the potential energy curves (PECs) and nuclear ground state deformation parameters (β2) of 63Co and 63Ni. The blocking effects of the unpaired nucleon are considered using the equal filling approach for the odd-A system. Later, the β-decay properties, including the stellar weak rates and Gamow–Teller (GT) strength of 63Co and 63Ni, are studied using the proton-neutron quasiparticle random-phase approximation (pn-QRPA) model. The β2 values computed from the RMF model are employed in the pn-QRPA framework as an input parameter for the calculations of β-decay properties for 63Co and 63Ni. The stellar rates are compared with the projected shell model (PSM) results. For all densities, the pn-QRPA rates are found to be higher than the stellar rates computed via the PSM to a factor of 1.3 or more. The findings reported in the present investigation might be useful for simulating the late-stage stellar evolution of massive stars and the s-process of nucleosynthesis.]]></description>

        <description><![CDATA[Spin–orbital (SO) splitting in atomic nuclei results from the coupling between a nucleon’s spin and its orbital angular momentum, fundamentally influencing nuclear structure, especially near the magic numbers. This paper reviews the impact of various effects on SO-splitting, including tensor and weak-binding effects in neutron-rich and weakly bound nuclei, focusing on both theoretical interpretations and recent experimental results. The study summarizes new experimental results on SO-splitting in isotopes such as 34Si, 32Si, and 132Sn, showing a consistent smooth reduction in SO energy for weakly bound orbits, attributed to extended radial wave functions rather than a reduced SO potential strength. These findings reinforce the need for further experimental research with advanced radioactive ion beam facilities to understand the intricate behaviors of SO interactions in exotic nuclei.]]></description>
