Obiettivo Secondary beams of exotic nuclei opened up a new field of nuclear research giving unique information about the nuclear structure of weakly bound nuclei and new types of nuclear decays. In experiments of the first generation the halo structure of light drip-line nuclei was discovered, nuclear absorption radii were measured and scattering experiments in inverse kinematics were carried out.The main efforts in the project will first concentrated on making and starting up the high efficiency fragment-separator COMBAS (Dubna, Russia) for collection and separation of short-lived unstable nuclei with ultra-small yields and with large angular and momentum dispersions produced in the processes of projectile fragmentation at the intermediate energies and, secondly, design of a focal plane detector on the base of the large tracking multilayer drift chamber with multiple identification capability (time-profection chamber TPG). In the research part the COMBAS separator with its high efficiency collection of drip-line nuclei is exploited in investigations of the particle stability boundary in the region of light elements using the method of direct synthesis of drip-line isotopes. This method will also be used in the study of the evolution of the nuclear shapes of exotic nuclei versus increase of neutron excess using elastic scattering unstable projectiles in the inverse kinematics and, in the future, in the study of the properties of beta-delayed multi-neutron emitters. The experience of the GSI group in Darmstadt, Germany, in these fields could clearly help to commission COMPAS and the design of a new focal plane detector TPC especially. Their contribution is also expected in the equipping of the TPC detector by high quality electronics and data acquisition programs.Extensive theoretical investigations of inelastic collisions by the Catania group in Italy is of great importance in possible direct observation of 'pigmy' resonances in neutron rich nuclei. It is predicted that there will be an important increase of the sub-barrier fusion cross-section induced by neutron-skin projectiles. The experience of the Catania accelerator group in calculations of beam dynamics is also very important for the developments of diagnostic and control systems of the fragment-separator COMBAS.
