Abstract

Masses of nuclides covering a large area of the chart of nuclides can be measured in storage rings where many ions circulate at the same time. In this paper the recent progress in the analysis of Schottky mass spectrometry data is presented as well as the technical improvements leading to higher accuracy for isochronous mass measurements with a time-of-flight detector. The high sensitivity of the Schottky method down to single ions allows to measure lifetimes of nuclides by observing mother and daughter nucleus simultaneously. In this way we investigated the decay of bare and H-like 140Pr. As we could show the lifetime can be even shortened compared to those of atomic nuclei despite of a lower number of electrons available for internal conversion or electron capture.All these techniques will be implemented with further improvements at the storage rings of the new FAIR facility at GSI in the future.

Present and Future Experiments with Stored Exotic Nuclei at Relativistic Energies

Journal Article Geissel, H; Litvinov, Yu; Boutin, D; ... - AIP Conference Proceedings

Recent progress is presented from experiments on masses and lifetimes of bare and few-electron exotic nuclei at GSI. Relativistic rare isotopes produced via projectile fragmentation and fission were separated in flight by the fragment separator FRS and injected into the storage ring ESR. This worldwide unique experimental technique gives access to all fragments with half-lives down to the microsecond range. The great research potential is also demonstrated by the discovery of new isotopes along with simultaneous measurements of mass and lifetime. Representative results from time-resolved Schottky mass spectrometry are compared with modern theoretical predictions. The measured isospin dependence of pairing-gapmore »« less

New Developments for Isochronous Mass Measurements of Short-Lived Nuclei

Journal Article Knoebel, R; Litvinov, S; Boutin, D; ... - AIP Conference Proceedings

The combination of the in-flight separator FRS and the storage-ring ESR at GSI offers unique possibilities for high accuracy mass and lifetime measurements of bare and few-electron fragments. Operating the ESR in the isochronous mode allows for measurements of revolution frequencies of stored ions without cooling. Isochronous Mass Spectrometry (IMS) can be applied to fragments with half-lives as short as several tens of microseconds. Newly developed magnetic rigidity tagging increases the resolving power of IMS to about 500000. IMS can be used to measure masses of nuclei with rates even lower than one ion per day, a property also neededmore »« less

New results with stored exotic nuclei at relativistic energies

Conference Bosch, F; Boutin, D; Fastermann, T; ...

Recently, much progress has been made with stored exotic nuclei at relativistic velocities v/c = 0.7. Fragments of {sup 208}Pb and {sup 209}Bi projectiles and fission fragments from {sup 238}U ions have been produced, separated in flight with the fragment separator FRS, and injected into the storage-cooler ring ESR for precision measurements. Precise masses of neutron-deficient isotopes in the lead region have been measured with time-resolved Schottky Mass Spectrometry (SMS). A new isospin dependence of the pairing energy was observed due to the improved mass accuracy of typical 1.5 x 10{sup -7} (30 keV). New masses of short-lived neutron-rich fissionmore »« less

Status of the ESR and Prospects for Radioactive Ion Beams

Conference Franzke, B; Beckert, K; Groening, L; ...

This contribution presents the status of the Experimental Storage Ring ESR at GSI after nearly 10 years of experiments with electron-cooled primary and secondary heavy ion beams, and discusses possible upgrades for the near future. The major fraction of the ESR beam time was dedicated to atomic spectroscopy experiments with fully stripped or few-electron heavy ions up to uranium. Remarkable nuclear physics results came, so far, mainly from the precise Schottky mass spectrometry with cooled radioactive fragments. The experimental program of a future--very likely modified--ESR aims at nuclear physics experiments with secondary, neutron-rich or neutron-deficient nuclides with lifetimes in themore »« less
From J. J. Thomson to FAIR, what do we learn from Large-Scale Mass and Half-Life Measurements of Bare and Few-Electron Ions?

Journal Article Muenzenberg, Gottfried; Geissel, Hans; Litvinov, Yuri - AIP Conference Proceedings

This contribution is based on the combination of the talks: 'What can we learn from large-scale mass measurements', 'Present and future experiments with stored exotic nuclei at relativistic energies', and 'Beta decay of highly-charged ions'. Studying the nuclear mass surface gives information on the evolution of nuclear structure such as nuclear shells, the onset of deformation and the drip-lines. Previously, most of the masses far-off stability has been obtained from decay data. Modern methods allow direct mass measurements. They are much more sensitive, down to single atoms, access short-lived species and have high accuracy. Large-scale explorations of the nuclear massmore »« less
