Laser spectroscopy is a versatile tool to unveil fundamental atomic properties of an element and information on the atomic nucleus. Up to the chemical element fermium (Z=100), a limited number of long-lived isotopes can be produced in macroscopic amounts through irradiation of actinide samples in reactors where they undergo neutron capture and successive beta decay. Heavier elements and more...
The Facility for Rare Isotope Beams (FRIB) at Michigan State University has recently commenced operation and delivered first radioactive ion beams to its users [1, 2]. Besides its portfolio of fast, stopped, and re-accelerated beams, isotope-harvesting techniques are being developed to exploit isotopes that are otherwise lost to the beam dump [3]. The study of radioactive molecules receives...
Laser spectroscopy measurements can provide information about fundamental properties of both atomic and nuclear structure. These measurements are of particular importance for the heaviest actinides and superheavy elements, where data are sparse. Recent resonance-ionization-spectroscopy experiments at GSI, Darmstadt, Germany, have focused on in-gas-cell measurements using the RADRIS technique...
Collinear laser spectroscopy is a powerful tool for the study of the basic properties, such as the spins, magnetic moment, electric quadrupole moments and charge radii, and the related structure of exotic nuclei far from β-stability line [1]. In order to study these properties of unstable nuclei at Radioactive Ion-beam Facility in China, we have developed a collinear laser spectroscopy (CLS)...
