Summary: The project is axed on nuclear physics with heavy ions, i.e. phenomena connected with nucleus-nucleus collisions at energies of the order of 10 MeV to 1 GeV per nucleon. The following features are given particular attention: a) fragmentation, statistical (production of entropy) and collective behaviour (various types of flow) in nucleus-nucleus collisions at energies of up to 1 GeV per nucleon; b) clustering in atomic nuclei, quasi molecular configurations, resonant behaviour of heavy-ion collisions; c) transport equations applied to nuclear matter and collisions of nuclei; d) equilibrium and preequilibrium processes following nucleus-nucleus collisions.

Keywords: nuclear reactions induced by heavy-ions, cluster and quasi-molecular stracrure, nuclear equation of state, entropy, collective flow, itermediate mass fragments

Research goals: The aim of the project is to study the properties of nuclearmatter at high pressure and temperature as well as the structure of the atomic nucleus in its extreme shapes, using, as a tool, the collisions of heavy-ions in the energy range of 10 - 1000 MeV/nucleon. The results that cumulated in the past 5 years,published in about 35 articles in leading international journals (Physical Review Letters, Physical Review, Physical Letters) ,comprise: - the determination by measurement of the active particle-emission volume in a nucleus-nucleus collision; - an independent measuremant of the entropy for Au+Au collisions at several hundred MeV/nucleon; - the calculation of the initial number of degrees of freedom that share the energy in a nucleus-nucleus collision; - the explanation of alpha-particle scattering on light nuclei in the frame of the quasimolecular picture of resonances; - the role of the intermediate mass fragments in central collisions of gold nuclei at 150 MeV/nucleon; - the importance of particle exchanges for the appearance of resonances in the reactions with carbon-14.
