Identification of Na 17 Ground State and Mirror Symmetry Violation with C 17
The ground state of the three-proton emitter $^{17}\mathrm{Na}$ has been identified. Energy correlations between the protons and the $^{14}\mathrm{O}$ residue indicate that its decay is sequential initiated by the emission of a single proton to the ground state of $^{16}\mathrm{Ne}$ followed by simultaneous emission of two protons to the ground state of $^{14}\mathrm{O}$, and the derived total decay energy is 4.45(3) MeV. The angular distribution of the proton from the first step indicates that this emission is $d$-wave and only consistent with a spin parity of $5/{2}^{+}$. This assignment is consistent with state-of-the-art Gamow shell-model calculations. As the ground state of $^{17}\mathrm{C}$ is $3/{2}^{+}$, the assigned spin parity of its mirror $^{17}\mathrm{Na}$ indicates that the pair presents a new case of ground-state mirror symmetry violation (GMSV). Unlike other GMSV cases, which arise solely from either a Coulomb induced shift or deformation effects, the $^{17}\mathrm{Na}/^{17}\mathrm{C}$ case is generated by differences in the many-body correlations.- 2 September 2026

Simulation and Experiment on Spatial Resolution of Fast Neutron Tomography using Associated Particle Technique
Fast neutron tomography has significant advantages in the non-destructive testing of large high-density materials. However, scattered neutrons and induced fission neutrons can severely degrade imaging quality. Associated Particle Imaging (API) enables electronic collimation using the time-of-flight technique. This paper investigates the factors influencing the spatial resolution of an associated α-particle fast neutron transmission imaging system through Monte Carlo simulations and experiments. Imaging models with different phantoms and targets of various sizes were developed using Geant4. Several reconstruction algorithms were compared, including Filtered Back Projection (FBP), Conjugate Gradient Least Squares (CGLS), Simultaneous Iterative Reconstruction Technique (SIRT), and SIRT-Total Variation (SIRT-TV). SIRT-TV performed best in suppressing artifacts and enhancing image quality. Under ideal point source conditions with a source-object distance of 250 mm and a source-detector distance of 2000 mm, its spatial resolution reached 0.467 lp/mm (2.142 mm). Increasing the target diameter significantly degraded resolution and deteriorated image quality. Subsequently, an experimental platform consisting of a 99-module pixelated plastic scintillator neutron detector array and a position-sensitive α detector was established, and transmission imaging experiments were conducted on a stainless-steel ring sample. Backgrounds from γ-rays and scattered neutrons were rejected using Pulse Shape Discrimination (PSD) and neutron–α time-coincidence techniques. The reconstructed images show clear structure, with a maximum dimensional error of 2.5 mm for the sample. The experimental results validate the accuracy of the simulation model. This study provides theoretical and experimental support for the application of API in the nuclear industry and security inspection.

β Decay of 20Na
20Na is a well-known -delayed emitter, owing to the large decay energy of 20Na above the α + 16O threshold in the daughter nucleus 20Ne. In this work, the decay property of 20Na is investigated in detail via the β-γ β-α and β-γ-α coincidence spectroscopy. As the day-one experiment of the Beijing Rare Isotope Facility (BRIF), the intense 20Na beam was produced using the Isotope Separator On Line (ISOL) technique through the 100 MeV proton bombarding a stack of MgO as a thick target. Specific interest was focused on the exotic decay mode of 20Na; the previously reported low-energy α lines at 713 and 846 keV were confirmed, and several weak β-γ-α decay sequences were clearly identified for the first time, thanks to the strong resolving power of α-γ coincidence spectroscopy. The decay properties of 20Na are compared to the shell model calculation, which agree reasonably well with the allowed β transition strengths and subsequent electro-magnetic transitions with the use of the sd shell-model space with the USDB interaction.Open Accessβ Decay of 20Na
