• nucleosynthesis of heavy elementsin explosive stellar events proceedsalong chains of unstable nuclei
beams of unstable nuclei provide:• masses, decay-, reaction rates• stellar conditions in terrestrial
laboratories (highly charged ions)
improved modelling ofsynthesis process

Challenging problems in non-perturbative QCDChallenging problems in non-perturbative QCD
• Why are quarks confined within hadrons?• How are hadrons constructed from their constituents?•What is the relation of parton degrees of freedom and thelow energy structure of hadrons?
• What is the origin of hadron masses?• How are hadrons modified when embedded in nuclei?• Do glueballs (ggg) and hybrids (qqg) exist?
⇒ New experimental approach: antiproton beams up to 15 GeV/c
