Structure and Reactions of Exotic Nuclei
PI32 Collaboration (theory group,
but .) Some conclusions (keywords)
2

• Isotopic dependence of nuclear properties
• effective interactions in finite nuclei
• (to be used in different nuclear models,
• from no-core shell model for
• light systems to standard shell
  model,
• RPA, etc)
• behaviour of single-particle and collective
  states
• interplay of T 0 and 1 pairs
• Obs need for full information from structure
• calculation not only energies and EM
  transitions,
• but also spectroscopic factors for 1 and 2
  particle
• asymmetric nuclear matter

3

• Treatment of continuum in nuclear structure
• extension of models (e.g. shell model)
• to include continuum states
• unbound many-body states
• effects on (weakly) bound states
• new concepts
• model case (working laboratory) to compare
• different approaches
• clustering and pairing
• (obs reaction mechanism for pair transfer
• with unstable intermediate states)

4

• Treatment of continuum in nuclear reactions
• necessary consistency with nuclear
• structure inputs
• different reaction models, but need for
• overall description of elastic, break-up,
• transfer, fusion processes
• (no ad hoc descriptions)
• effect of continuum on potentials and
• transition potentials
• need for a model case (hamiltonian,
• channels,.) for comparing different
• approaches

Low-energy nuclear structure and reactions
vs Intermediate
energy reactions Points of contact (physics of
isospin, effective interactions, phase
transitions, ) but need for bridges
