“…The Padova group has similar and complementary lines of research as the Pisa group as far as reaction mechanisms are concerned. However it has a special interest for a somehow lower energy domain where fusion and the coupling to breakup channels are particularly important [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Besides it is active in studying structure problems such as: -Study of the pairing correlations in low-density nuclear systems, as in the external part of halo nuclei.…”

The INFN (Italian National Institute for Nuclear Physics) has approved a national theoretical network on "Structure and Reactions with Exotic Nuclei". The project involves the INFN branches of Laboratorio Nazionale del Sud, Padova and Pisa. The aim of the project is to start coordinating and to homogenize the research already performed in Italy in this field and to strengthen and improve the Italian contribution on the international scenario. Furthermore it aims at creating a solid theoretical structure to support future experimental facilities at the INFN national laboratories such as SPES at LNL and EXCYT at LNS. A review of present and future activities is presented.been carried out within pre-existing national projects related to a wide spectrum of themes of nuclear dynamics, structure and reactions using many body techniques, shell model, collective modes and semiclassical or fully quantum mechanical approaches to peripheral and central reactions such as transfer and breakup, fusion, elastic scattering via microscopic optical potentials, multifragmentation.The goal of our project is to start coordinating and homogenizing such efforts to improve our mutual understanding, and to strengthen the Italian contribution on the international scenario. Furthermore our efforts will help creating a solid theoretical structure to support future experimental activities at the INFN national laboratories.In fact, in the last two decades, the use of radioactive beams of rare isotopes in several laboratories around the world (REX-ISOLDE at CERN, GANIL in France, GSI in Germany, CRC, Louvain la Neuve in Belgium, RIKEN in Japan, DUBNA in Russia, Argonne, MSU, Oak Ridge, Notre Dame in USA , etc.) has provided new research directions and an increasing number of researchers all over the world is converging on such subject. The INFN in Italy is also heavily involved in this field. The facility EXCYT and the large acceptance spectrometer called MAGNEX are being completed at Laboratorio Nazionale del Sud. On the other hand the first step of the SPES project at the Laboratorio Nazionale di Legnaro has been approved in the form of a proton driver. Furthermore the INFN is promoting the new European Radioactive Beam Facility (EURISOL). Members of our collaboration are actively participating in NuPECC working groups, in particular in the preparation of "The Physics Case" for EURISOL, whose report is available at http://www.ganil.fr/eurisol/Final Report/A-Physics-Case-20-Dec-02.pdf, and in general of the NuPECC Long Range Plan.The relatively new subject of exotic nuclei is of fundamental importance because while all existing theories for the nuclear interaction and the many body nuclear structure have been based on the study of stable nuclei, very little is known about the way in which standard nuclear models work for the description of unstable nuclei with anomalous N/Z ratio. Important questions to answer are for example: the isospin dependence of the effective nuclear interaction, the modification of the traditional shell sequence with ...

“…We give a particularly simple template model where enabled and occurring actions as well as data observations are uniformly treated as facts: sets of facts describe situations, finite or countably infinite sequences of situations describe life cycles, and sets of life cycles describe template processes. Amazingly enough, this simple model is powerful enough to serve as a semantic basis for languages like TROLL [JSHS91,Ju93].…”

We give a survey of concepts for system specification and design based on the viewpoint that a system is a community of objects. Objects are self-contained units of structure and behavior capable of operating independently and cooperating concurrently. Our approach integrates concepts from semantic data modeling and concurrent processes, adopting structuring principles partly developed in the framework of object-orientation and partly in that of abstract data types. A theory of object specification based on temporal logic is briefly outlined.

“…In this paper, we outline a theory of object-oriented information systems specification and design, focussing on a formal semantics for TROLL. In his recent dissertation [Ju93], the second author offered a close to complete formal semantics adopting OSL [SSC92] which is based on temporal logic. We extend this approach in order to allow for a complete semantic description, including also dynamic object roles and phases as well as object creation and deletion.…”

Information systems are reactive systems with a database. For their specification and design, concepts from conceptual data modeling and concurrent processes are relevant. In this paper, we outline a unifying theory borrowing ideas from these approaches and from abstract data type theory. Our approach utilizes a variant of temporal logic. It has been used to give a formal semantics for TROLL, the objectoriented information systems specification language developed at TU Braunschweig.
