Laser Spectroscopic Determination of Nuclear Ground-State Properties — •Wilfried Nörtershäuser — Technische Universität Darmtadt, Institut für Kernphysik

Ground-state properties of nuclei can be extracted from the optical spectrum of an isotope or isomer with high accurcay and independent of a specific nuclear model. Particularly for short-lived isotopes, this is the method of choice to determine spins, magnetic dipole and electric quadrupole moments, and changes in nuclear charge radii along a chain of isotopes. Spectroscopy of stable isotopes is often used to calibrate the atomic parameters required to extract the nuclear property or to determine reference values. Moreover, laser spectroscopic techniques can also be used to prepare ion beams in a specific energy level, charge state, or polarized beams. This can facilitate the determination of nuclear ground-state properties as well as other atomic physics and nuclear physics experiments. Recent progress in these fields is presented.
