Collinear laser spectroscopy is a powerful method that is being used since the 1970s [1] to investigate optical transitions all across the nuclear landscape. It is especially well suited to investigate short-lived radioactive isotopes [2, 3]. The precise measurement of atomic transition frequencies gives access to a variety of nuclear properties, such as the charge radius via the isotope shift or the nuclear spin, as well as the magnetic dipole and the electric quadrupole moment through the hyperfine structure [4, 5, 6].
