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.
By identifying a previously overlooked ground state in La that is 221 keV/c² lighter than previously reported, this study resolves contradictory mass measurements and eliminates an anomalous prominence in lanthanum two-neutron separation energies, revealing a new kink structure attributed to a nuclear shape transition around .
This study utilizes the JYFLTRAP double Penning trap to precisely measure the electron-capture value of Sn, identifying a favorable allowed transition to a low-lying excited state in In that, when combined with advanced atomic corrections, significantly enhances sensitivity for future electron neutrino mass measurements.
This paper demonstrates that while GS20 is a proven portable neutron detector, CLYC detectors are superior for neutron resonance transmission analysis in high gamma-radiation environments typical of thorium-based safeguards due to their strong pulse-shape discrimination capabilities, which yield significantly more precise measurements despite longer decay times.
This paper introduces HISP, an open-source simulation tool used to demonstrate that baking is the most effective method for removing tritium from ITER's plasma-facing components, significantly outperforming Glow Discharge Conditioning and low-power deuterium pulses which had minimal impact on the final inventory.
Using the MIMAC-35 cm detector, researchers successfully measured and identified 51 thermal neutron capture events in hydrogen by discriminating 1.3 keV deuteron tracks from a background of over 11 million events, demonstrating the detector's capability to search for low-energy rare events without shielding.
This paper reports new measurements and analysis of Adiabatic Fast Passage (AFP) efficiency in various solid polarized target materials, introducing a joint manipulated-lineshape method to extract vector and tensor polarization components and demonstrating a strong dependence of AFP efficiency on initial polarization.
This paper proposes a beam-energy scan of isobaric collisions (Ru+Ru vs. Zr+Zr) to precisely measure electric-charge transport and distinguish between competing microscopic mechanisms of conserved-charge redistribution in QCD matter by comparing the rapidity dependence of charge and baryon transport.
This paper critically examines the origins of common recoil-order approximations in traditional -decay formalisms, which have become a limiting factor in precision Standard Model tests due to recent advances in nucleon-level radiative corrections, while addressing resolved issues and identifying open questions in the context of progress in ab initio nuclear theory.
This study predicts the existence of deformed -wave neutron halos in silicon isotopes Si by integrating deformed relativistic Hartree-Bogoliubov theory with Glauber model reaction analyses, supported by consistent evidence from multiple structural criteria and reaction observables.
The paper introduces JetPrism, a configurable Conditional Flow Matching framework that addresses the misleading nature of standard training losses in nuclear physics simulations by establishing a multi-metric evaluation protocol to ensure generative models achieve true physical fidelity and convergence beyond generic loss indicators.
