The Moon provides a unique environment for investigating nearby astrophysical events such as supernovae. Lunar samples retain valuable information from these events, via detectable long-lived "fingerprint" radionuclides such as $^{60}$Fe. We are developing the accelerator mass spectrometry (AMS) method for detecting $^{60}$Fe using the HI-13 tandem accelerator at the China Institute of Atomic...
As member of the Tz=-2 family, 28S is a nucleus rather light near the proton drop line, and has high β-delayed proton (βp) branching ratio. Precise β-decay spectroscopy of proton-rich nucleus 28S serves as a powerful tool to study the isospin symmetry breaking, and to test the unitarity of CKM matrix through the superallowed Fermi transition between isobaric analog states. ...
A non-zero electric dipole moment of the neutron (nEDM) would violate the CP symmetry and be related to baryon asymmetry in our universe. The TRIUMF Ultracold Advanced Neutron (TUCAN) collaboration is commissioning a world-leading ultracold neutron (UCN) source for such precise measurements of the nEDM. With such an intensive UCN source, the TUCAN collaboration aims to push the statistical...
High-spin states of $^{67}$Ga have been studied via the $^{58}$Ni($^{12}$C, 3p)$^{67}$Ga fusion-evaporation reaction at a beam energy of 50.4 MeV. Three negative-parity bands and three positive-parity bands in $^{67}$Ga are established. The observation of one new $E3$ transition linking the positive-parity $\pi 1g_{9/2}$ band and negative-parity $\pi 2p_{3/2}$ band provides evidence of octuple...
Constraining the equation of state (EoS) of nuclear matter remains one of the key open questions in both nuclear physics and astrophysics, with significant implications for phenomena such as neutron stars and supernova explosions. One approach is to investigate the differences in proton and neutron density distributions across isotopic chains, which are expected to provide a valuable insight...
Big Bang Nucleosynthesis (BBN) refers to the nuclear reactions that occurred approximately from 10 seconds to 20 minutes after the birth of the universe. These reactions produced light elements, mainly $^2$H, $^3$He, $^4$He, and $^7$Li. The standard BBN model reproduces the abundances of these elements with high precision, except for $^7$Li. This agreement is regarded as strong evidence that...
The carbon-carbon fusion reaction serves as a crucial reaction for stellar evolution and explosive events, significantly influencing the evolution of massive stars and the explosion of superburst in the Universe. Despite decades of research, there remains considerable uncertainty in the cross section, particularly at stellar energies below E_{C.M.}=3MeV. The extrapolation techniques cannot...
Recent measurements of two-particle correlations within jets in high-multiplicity pp collisions at √s = 13.6 TeV reveal flow-like patterns among jet constituents. Such effects were previously considered unique to heavy-ion collisions, suggesting that a hot, dense QCD medium may form even inside jets in small systems. As this medium hadronizes, substantial final-state hadronic interactions can...
