The $\mathrm{^{18}O}(p, \alpha)\mathrm{^{15}N}$ reaction plays a crucial role in influencing the abundances of key isotopes such as $\mathrm{^{19}F}$, $\mathrm{^{18}O}$, and $\mathrm{^{15}N}$ in asymptotic giant branch (AGB) stars. This reaction may offer a potential mechanism to explain the discrepancies between observational data and theoretical model predictions.

The existence of the island of stability has been predicted [1]. One of the major topics in nuclear physics is the production of $^{298}\mathrm{Fl}$, which is located at the center of this island.
A previous study [2] predicted that synthesizing a compound nucleus more neutron-rich than $^{298}\mathrm{Fl}$ (e.g. $^{304}\mathrm{Fl}$) may offer an advantage in terms of production probability....
As a complex, large-amplitude deformation quantum many-body system, nuclear fission reflects the competition between single-particle and collective behaviors, leading to the coexistence of multiple fission modes for the same fissioning nucleus. Both past and recent experiments indicate that $^{187}$Ir undergoes predominantly symmetric fission, while several theoretical predictions favored...
We investigate the cluster structure of $^{10}\mathrm{C}$ using a microscopic four-body $\alpha + \alpha + p + p$ cluster model within the Generator Coordinate Method (GCM) framework. The calculated low-lying energy spectrum is in good agreement with the experimental data. Based on the analysis of reduced width amplitudes (RWA) and spectroscopic factors (SF) for the two-body decay channels...
The nuclei, characterized by large $N/Z$ ratios, are often referred to as exotic nuclei and challenge the traditional understanding of nuclear shell structure. The conventional magic numbers, such as $N=$8, 20, 28, etc., tend to diminish or vanish, and new magic numbers emerge in the exotic systems. In this work, we investigated the appearance of new magic numbers at $N=32$ and 34 and their...
Nowadays, searching for $\alpha$ condensation around a core nucleus is an interesting topic. Previous theoretical studies predicted $^{16}$O+2$\alpha$ condensed states. However, there was strong mixing with non-resonant states and it causes the identification of true resonant states non-trivial.
To address this issue, we aim to provide a more robust theoretical verification of the...
Beta decay is one of the fundamental weak interaction processes in nuclear physics that is crucial in shaping our understanding of nuclear structure. It also provides important insights into various astrophysical phenomena like r−process which is responsible for forming about half of the heavy elements in the universe beyond iron [1]. In this talk, I will discuss the beta decay properties...
Exploring the nuclear shell structure of neutron-rich N = 50 nuclei is one of the most interesting and mysterious phenomena in nuclear physics, and it has become the forefront of both experimental and theoretical research in recent years. We have constructed the shell model Hamiltonian in the π(f p)-ν(sdg) model space based on an ab initio approach using VS-IMSRG(3f2) with minimal...
improve the harmonic oscillator model and test its performance for nuclear charge radii and neutron skin thicknesses
Recent $B\rho$-defined isochronous mass spectrometry experiments have determined the masses of proton-rich nuclei such as $^{23}$Si, $^{26}$P, $^{27}$S, and $^{31}$Ar. These results confirm the bound nature of these isotopes and establish the location of the proton dripline for several isotopic chains. Notably, the measured mirror energy differences (MEDs) exhibit clear deviations from mirror...
