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 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.We hope to attract some part of the Napoli and Milano nuclear structure groups in order to have a wider range of competences.

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.

Can a good percentage of our theoretical work be considered unrelated to experiments ? Is all experimental work well oriented? Reaction theory K є Structure theory K є Experiments M є

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- experimentalists 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 N=Z nuclei up to 100Sn. Study of the interplay of T=0 and T=1 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 etc…have 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
