Objectif This research proposal is devoted to the investigation of dynamical behaviour of electronic and ionic subsystems in metal clusters and fullerenes in various physical processes, by describing the dynamics of the electronic subsystem of a cluster, it is planned to develop a new self-consistent description for a finite many particle system, which is characterized by the finite range of the effective interaction and the correct asymptotic behaviour of the self-consistent mean field. The new theory will be applied to the description of finite systems such as metallic clusters and atomic nuclei with the aim to obtain a more accurate description of both ground state and excited state properties, a correct description of both collective plasmon-like excitations and single-particle excitations.It is planned to develop dynamical model describing vibrations of ions in a cluster and their interaction with the quantized motion of electrons in the field of the ionic core. Using the dynamical model, a number of physical processes involving clusters (photoabsorption, scattering, attachment, photon emission), where dynamics of ions is important, will be treated and the cross sections of these processes will be obtained. Using the dynamical model, it is planned to obtain the temperature dependence of the widths of electron excitations in clusters and to explain the dependence of the cross sections of the processes mentioned above on the cluster temperature. Particular attention will be paid to the investigation of the temperature dependence of multipole plasmon resonance patterns in clusters, which can be excited by photon and electron impact. The influence of ion vibrations on the dynamics of the electron subsystem of a metal cluster in collision with a multicharged ion will be studied as well, because in this case one can expect enhancement of the role of ions dynamics due to the presence of the strong Coulomb field in the system.Expanding our study of the vibration dynamics of the ions in a cluster, the problem of cluster fragmentation under various circumstances will be tackled. The opposite process of the formation of cluster systems, consisting of an atom or an ion embedded into a cluster will be studied as well. Theoretical development of one-electron approaches and calculated data on changes in energy spectra, wave functions and abilities of atoms to expand or contract upon embedding into a spherical spatial confinement with finite wells will be made.The present project is represented by the seven research teams: three INTAS members teams (Professor W.Greiner Germany; Professor C.Guet France; Professor J-P.Connerade United Kingdon) and four NIS teams (Professor V.K.Ivanov Russia; Professor V.R.Shaginyan; Russia; Dr A.V.
