Abstract: An overview is given on very recent atomic physics experiments at accelerators using radiofrequency or laser spectroscopy. Very high accuracy and, in addition, extreme sensitivity are reached by cooling and storage in ion traps. These investigations address basic properties of exotic nuclei (nuclear binding energy, spin, electromagnetic moments and charge radii), the study of ions in their highest charge state (atomic binding energy, hyperfine structure splitting and g-factor of the bound electron in hydrogen-like ions as, for example, in U91+) or the high-accuracy determination of fundamental constants such as the mass of the electron or the fine structure constant.
