✦ Synopsis


We present results from two methods of direct mass measurements of relativistic exotic nuclei stored in the storage ring ESR. Schottky Mass Spectrometry (SMS) with electron-cooled ions is well suited for long-lived nuclei (T 1/2 10 s), and the Isochronous mass measurements (IMS) for hot fragments (T 1/2 1 µs). In addition, SMS provides information on nuclear lifetime for bare and highly ionized atoms.
