The triaxial degree of freedom in nuclei has an important role in the shape evolution. The neutron-deficient and neutron-rich Mo isotopes provide a good example. The large collectivity of a neutron-deficient nuclide $^{84}$Mo leads to the isospin-symmetric island of inversion, and the large triaxiality is expected from the state-of-the-art shell model calculation [1]. For the nuclides lying on...

Nuclei near the doubly magic nucleus $^{100}$Sn (N = Z = 50) have been extensively studied to investigate nuclear structure, including shell evolution, seniority effects, and proton–neutron interactions. In this work, $^{94}$Pd with N = Z + 2 was investigated with a focus on isovector (T = 1) and isoscalar (T = 0) neutron-proton pairing using the fast-timing measurement. Half-lives of yrast...

Cryogenic gas targets are widely used in low-energy nuclear experiments for studies of nuclear astrophysics and nuclear structure. Compared with solid targets such as CH$_{2}$ and CD$_{2}$, cryogenic gas targets offer high purity and high density. These advantages reduce unwanted background contributions and enhance reaction yields, thereby improving the sensitivity of nuclear physics...

30. Development and Evaluation of a Quadrant Silicon Pad Sensor for the TexAT Active Target DetectorHyeyoung Lee (CENS, IBS)24/07/2026, 11:29
For low-energy rare-isotope beam experiments, a 5 x 5 cm$^2$ quadrant silicon pad sensor was developed for the TexAT active target system. To prevent premature breakdown in large-area segmented sensors, three guard-ring configurations (G6, G9, G14) were investigated via TCAD simulations and experimental measurements. Simulations proved that the G9 design, using a graded-spacing strategy,...

We establish a universal baseline for the widths of near-threshold single-neutron resonances in L>0 partial waves. The baseline arises from discrete scale invariance at zero energy in the finite square-well potential and depends only on geometry, angular momentum, and resonance energy. Comparison with data shows that it provides a robust benchmark, while deviations caused by Woods-Saxon...

The charge-dependent nucleon-nucleon ($NN$) interaction plays a crucial role in understanding the nuclear structure and reaction problems. In this work, we explore the charge-dependent $NN$ interaction in covariant chiral effective field theory. By incorporating the isospin-breaking contributions, we derive the charge-dependent covariant chiral $NN$ potential up to next-to-next-to leading...
