Taking the full advantages of the cooled and bunched radioactive ion beams delivered from a gas-filled linear Paul trap, collinear laser spectroscopy experiment could reach a higher resolution and sensitivity to access the ground-state properties (spins, electromagnetic moments and charge radii) of the radioactive nuclei [1]. These nuclear properties allow for a more detailed investigation and understanding of the exotic nuclear structure, e.g. shell evolution, nuclear magicity, and deformation [2-3]. Additionally, as the basic properties of the atomic nuclei, they also offer a prominent test of the advanced nuclear many-body methods and nuclear interactions [2-4].
In this talk, high-resolution laser spectroscopy experiments and the recent results on the properties and structure of neutron-rich nuclei (e.g. 46-49Sc and 81-82Zn) in the calcium and nickel regions will be presented and discussed [4,5]. Furthermore, recent progress and near-future plan on the development of high-resolution laser spectroscopy together with the RFQ ion trap in China will be introduced.
