Production of radioactive ion (RI) beams at RIKEN RIBF using the BigRIPS fragment separator requires dedicated studies of RI-beam separation and particle identification (PID), particularly for heavy-ions or low-energy beams. Challenges arise from the charge-state change and inaccurate energy loss predictions. While post-experiment analysis provides valuable insights for further improvements,...

The Resonance Ionization Laser Ion Source (RILIS) has become the most-used ion source type in the ISOL (Isotope Separator On-Line) facilities worldwide due to its element selectivity and high ionization efficiency. The hot-cavity type RILIS developed at RAON is based on resonant excitation of atomic transitions by the frequency tuned laser beams which are overlapped temporally and spatially...

Understanding alpha-condensate states is essential for investigating the properties of nuclear matter in low-density regions. Theoretically, such states are expected to exist in nuclei with mass number $A < 40$. There has been a general consensus that the ground state ($0^+_1$) of $^8$Be and the $0^+_2$ state of $^{12}$C correspond to 2$\alpha$ and 3$\alpha$ condensate states, respectively....

Abstract The global demand for medical isotopes is continuously expanding. Currently, ultra-compact cyclotrons built with mature superconducting technology are highly favored due to their high beam intensity, small footprint, and significant commercial advantages. However, their strong magnetic fields, ultra-compact structure, and the high beam intensity required for high production...

Abstract The medical isotope Astatine-211 (At-211), an alpha emitter, has significant application prospects in Targeted Alpha Therapy (TAT). Due to its high linear energy transfer (LET) and short range characteristics, it can effectively destruct cancer cells while causing relatively little damage to the surrounding healthy tissues. The production of At-211 is mainly achieved by bombarding...

Mr Hanrui Hu (Peking University)
Nuclear properties are closely connected to nuclear structure and nucleon-nucleon interactions, making them essential for exploring various novel phenomena that emerge in exotic nuclei. Laser spectroscopy is a powerful technique for investigating nuclear properties of unstable nuclei by probing the hyperfine structure (HFS) of their surrounding electrons. Such HFS effect contributes only about...

Atoms of different chemical elements exhibit characteristic spectra that serve as their unique fingerprints. Our knowledge of their spectra has allowed the identification of heavy elements in extragalactic stars, and even in neutron star mergers where half of the elements are thought to be produced.
Till date, very little is known about the atomic structure of the heaviest elements, which...

The inelastic scattering and gamma decay coincidence measurement, e.g., ($p$,$p'$$\gamma$) and ($\alpha$,$\alpha'$$\gamma$), is a great tool to study nuclear structures. In order to realize the measurement, we performed campaign-type experiments using high-resolution spectrometer Grand Raiden and Germanium detector array CAGRA at Research Center for Nuclear Physics (RCNP), Osaka University in...

The ISAC facility at TRIUMF hosts two high purity germanium detector arrays which allow for world-class gamma-ray spectroscopy experiments: TIGRESS (mainly used for reaction studies) and GRIFFIN (for decay studies). These detectors are typically utilized in radioactive beam experiments, however the finite beamtime available at ISAC results in regular periods of downtime where the detector...

A $\mu^+$SR technique has been used to measure self-diffusion coefficients and activation energies of ions in cathode materials such as Li$_x$CoO$_2$. [1] However, direct determination can be challenging due to the use of models such as a dynamic Kubo-Toyabe function, as well as difficulties in distinguishing muon diffusion itself from Li$^+$ diffusion at high temperatures.
