Nucl-Ex represents the dynamic frontier where scientists probe the fundamental building blocks of matter through high-energy experiments. By smashing particles together at incredible speeds or observing rare cosmic events, researchers uncover the forces that govern our universe and test the limits of our current understanding of physics.
At Gist.Science, we ensure these breakthroughs reach a broader audience by processing every new preprint in this field directly from arXiv. For each study, we provide both a clear, plain-language explanation of the core discoveries and a detailed technical summary for those seeking deeper insights. Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This paper establishes a non-perturbative Green's function formalism that models sub-barrier proton-nucleus scattering via a surface delta-shell impurity, successfully predicting resonance energies for , , and systems while distinguishing between weak-coupling threshold states and saturated geometric plateau states.
This study resolves a long-standing discrepancy in the to transition strength of Fe by using Coulomb-excitation measurements to demonstrate that previous lifetime data were overestimated due to outdated electronic stopping power models, thereby confirming the validity of shell-model predictions.
Using deuteron inelastic scattering in inverse kinematics with the CAT-M active target, researchers measured the isoscalar giant monopole resonance in Kr at 17 1 MeV to investigate the nuclear matter incompressibility and its isospin dependence.
This paper demonstrates the highest-frequency mechanically driven Mössbauer resonance to date by efficiently coupling an enriched Fe film to a 97.9 MHz surface acoustic wave, thereby enabling coherent control of nuclear transitions through the generation of absorption sidebands well above the nuclear linewidth.
This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.
This paper introduces a Bayesian protocol that combines full-spectrum template matching with probabilistic evidence evaluation to successfully identify single- and two-source neutron configurations from recoil and time-of-flight spectroscopy data with high statistical significance, even at low event counts.
This paper presents a theoretical analysis demonstrating that finite size and lifetime effects in heavy-ion collisions modify the momentum-space two-point correlation function of baryon density, resulting in an effective scaling exponent that matches the infinite-system value only within a specific, experimentally accessible momentum range.
This study addresses discrepancies in existing data by measuring proton-induced reaction cross sections on lanthanum across a 55–200 MeV energy range using stacked-foil activation, and subsequently improves the predictive accuracy of nuclear reaction models like TALYS through parameter adjustments to better support the production of the therapeutic radionuclide analogue Ce.
This paper calculates the tensor-polarized twist-3 parton distribution function for the spin-1 deuteron by applying twist-2 relations to the known twist-2 function , demonstrating that is comparable in magnitude to and suggesting that current and future facilities like JLab and the EIC are well-suited to investigate these higher-twist effects.
This study presents the first extraction of the nuclear level density and -ray strength function for the neutron-deficient In isotope using the Oslo method, revealing significant deviations from current model predictions and providing refined constraints for astrophysical -process simulations.
