This symposium was organized in order to discuss recent developments and future perspectives in intermediate-energy heavy-ion physics. The subjects included sub-barrier fusion, superheavy elements, fission; halo, skin nuclei; multi-fragmentation, collective flow, compression; properties of hot nuclei; high spin and exotic nuclear shapes; nuclear astrophysics; applications; facilities.

The book is a collection of papers from the Proceedings of the 5th Italy-Japan Symposium 'Recent Achievements and Perspectives in Nuclear Physics', held in Naples as part of the framework of the INFN-RIKEN Research Collaboration Program. The meeting was devoted to recent achievements and new challenges in the different fields of nuclear physics, with the aim to promote new collaborations between the two communities and thereby enhance the development of nuclear physics in the two countries. Particularly interesting are the topics dedicated to radioactive beams and innovative instrumentation: the prospects for future accelerators and experimental setups as well as novel future research directions. These projects are of key importance for the future of heavy ion nuclear physics.

This proceedings volume gives a consistent overview of various theoretical and experimental programs which study the dynamics of nucleus-nucleus collisions from low to ultra-relativistic energies. The contributions concentrate on the following topics: cold fragmentation of nuclear matter, pre-equilibrium and thermalization, thermal and chemical equilibration, fragmentation and correlations in intermediate energy collisions, dynamical properties of hot and dense nuclear matter in medium effects, resonance and strange nuclear matter, and signals of the deconfined state.High quality data obtained using experimental devices close to 4π geometries and recent theoretical developments are presented. They illustrate the significant progress made during the last few years in understanding the properties of nuclear matter in extreme conditions of pressure and temperature.This book serves as a graduate textbook and as a reference work on recent developments in this area.

These proceedings present the most recent progress made by Japanese and Italian researchers in the field of heavy ion physics. They cover both experimental and theoretical aspects from low energies (Tandem Van de Graaff accelerators) to medium energies (LINAC, Cyclotrons) up to relativistic energies (LHC at CERN).The majority of the experiments presented have been performed in the two largest Italian laboratories: LNL, Legnaro-Padova, with the Tandem + SC Linac (ALPI); LNS, Catania, with the Tandem + SC Cyclotron; and in one of the largest Japanese facilities: RIKEN, Saitama, with the Ring Cyclotron.The future Italian developments with relativistic heavy ions at LHC (CERN) are also presented, as well as experiments in collaboration with other laboratories, like JAERI, CNS (University of Tokyo), the Tandem Accelerator Center (Tsukuba), GANIL (France), and the Accelerator Laboratory in Munich, Germany.The highlights of the proceedings, and the area in which most experimental efforts are presently involved, are: research with radioactive ion beams at RIKEN with the RIPS separator; spectroscopy study at LNL with the GASP/EUROBALL 4πγ spectrometers; and intermediate energy hysics (deep inelastic, fragmentation) at LNS.Also presented are the future trends in Japan at RIKEN, RiBeam Factory, and JHP at KEK, and in Italy EXCYT at LNS and SPES at LNL. All these new developments are strongly connected with production and subsequent exploitation of radioactive ion beams, and offer a very promising, fertile future.
