Description
Electromagnetic properties of short-lived radionuclides serve as highly sensitive probes of the structural evolution of atomic nuclei far away from stability. Experimentally, they can be investigated using laser spectroscopy, where measurements of the atomic hyperfine structure provide access to the electromagnetic moments and charge radii of nuclear ground states and long-lived isomers. As these observables reflect both single-particle and collective (bulk) nuclear properties, laser spectroscopy offers crucial benchmarks for modern theoretical models of nuclear structure, particularly when tracing their evolution along isotopic chains from stability toward the limits of nuclear existence. Among the laser techniques developed at radioactive ion beam (RIB) facilities, collinear laser spectroscopy (CLS) has a long and successful history, providing high resolution experimental data.
In this talk, I will present recent scientific highlights from collinear laser spectroscopy, with a particular focus on novel CLS techniques developed to enhance the experimental sensitivity for studying the `most exotic’ radionuclides, available at today’s RIB facilities in quantities of only a few (tens of) ions per second, yet of intriguing physics interest.
