Summary
“All elements, all half-lives, all energies” (100MeV/u.....0...100keV)
Precision spectroscopy with swift and stopped nuclei
* Decay studies (decay modes, isomeric states)
* Ground state properties (masses, nuclear moments, radii)
Possible utilization of new probes (antiprotons)
* Synergies
* Complementarity
