摘要: Collinear laser spectroscopy is a powerful tool for studying the nuclear spins, electromagnetic moments, and
charge radii of exotic nuclei. To study the nuclear properties of unstable nuclei at the Beijing Radioactive Ion#2;beam Facility (BRIF) and the future High Intensity Heavy-ion Accelerator Facility (HIAF), we developed a
collinear laser spectroscopy apparatus integrated with an offline laser ablation ion source and a laser system.
The overall performance of this state-of-the-art technique was evaluated and the system was commissioned
using a bunched stable ion beam. The high-resolution optical spectra for the 4s 2S1/2 → 4p 2P3/2 (D2) ionic
transition of 40,42,44,48Ca isotopes were successfully measured. The extracted isotope shifts relative to 40Ca
showed excellent agreement with the literature values. This system is now ready for use at radioactive ion beam
facilities such as the BRIF and paves the way for the further development of higher-sensitivity collinear resonant
ionization spectroscopy techniques.
