摘要：

Isochronous and time-resolved Schottky mass spectrometry have been developed at the FRS-ESR facility of GSI for precise mass and half-life measurements of exotic nuclei. Both techniques are sensitive to single stored ions which makes them highly efficient. More than 1100 atomic masses have been measured meanwhile. Half-life measurements are performed with bare and few-electron ions whose decay modes can dramatically differ from the ones known in neutral atoms. After a brief description of the experimental methods, a short review of the obtained results and future perspectives will be presented.
