• Experimental external collaborations
• MAGNEX group LNS
• Signorini Co LNL
• De Angelis Co LNL (GSI)
• Pagano CHIMERA group LNSCT
• LPC, GANIL, GSI, Orsay, Strasbourg.
• MSU, Texas AM
• NOTE there is a theory group at LNS, LNF. LNGS
  but not at LNL.

• We intend to build up an efficient theory network
  to link Reaction Mechanism studies with Structure
  studies to support, confort and orientate
  experimental activities.
• We hope to attract some part of the Napoli and
  Milano nuclear structure groups in order to have
  a wider range of competences.
• In Pisa there is no experimental activity in
  Nuclear Physics.

3
In your opinion which percentage of the work
currently done world-wide in Nuclear Structure
will ever be tested by experiment?

• Some part is solely theoretical, and cannot be
  tested.
• Another part can, in principle, be tested, but
  will not be within our life time.
• A good proportion is tested because the theory is
  adjusted to experiment, but may be betrayed by
  other experiments in future.
• About 1/3 (?) will survive experiments even if
  some part of the calculation is adjusted. But
  this question makes sense after you define the
  "measure" of work.

4
Can a good percentage of our theoretical work
be considered unrelated to experiments ?Is
all experimental work well oriented?
Experiments M?
Structure theory K?
Reaction theory K?
5
How to make our field more efficient?

• Reorganization
• Up from the bottom approach thesis jointly
  supervised by a theoretician and an
  experimentalist. Students will be better
  educated, thesis will be more readeable, we
  will be forced to find not too technical
  problems, relationships theoretician-experimentali
  sts will improve.
• Mobility will automatically be implemented.

Our current interests and activities

• Isospin Dynamics in Reactions with Exotic Beams
  1) Isospin dynamics in low energy dissipative
  collisions 2) Isospin in Nuclear fragmentation.
• Finite Nuclear Systems in Brueckner Theory 1)
  BHF calculations of asymmetric and polarized
  matter. 2) Construction of the energy functional.
  3) Ground states and excitations of finite
  nuclei. 4) Neutron star crust.
• Structure and collective modes 1) Study of the
  pairing correlations in low-density nuclear
  systems. 2) Microscopic estimate of inelastic
  excitation to the low-lying continuum dipole
  strength via microscopic continuum RPA
  calculations. 3) Study of isospin symmetry in
  low- and high-spin states in medium-mass NZ
  nuclei up to 100Sn. Study of the interplay of T0
  and T1 pairing. 4) Study of nuclear structure
  with algebraic models.
• Reaction mechanisms 1) Elastic scattering and
  microscopic calculations of optical potentials.
  2) Breakup and transfer of weakly bound nuclei.
  3) One and two neutron halo systems. 4) Unbound
  nuclei studied via transfer and fragmentation.

TO THE SPEAKERS Please state at some stage of
your talk which is your Italian Connection

Short history of Italian Networks

• At University national level the class Nuclear
  Physics contains both th. and exp.
• This has helped people to find each other useful
  and keep very close contact. New jobs, promotions
  etchave usually been decided together.
• At INFN level instead the exp are one group
  (III),
• separated also from high energy, while we
  belong to the theory group (IV) dominated by
  high energy guys..this is a disaster for jobs
  and promotions
• but for research money and organization we
  have so called iniziative specifiche
  (dedicated projects), divided by area
