Scientific Programme:
The main goals are to predict and analyze properties of atomic nuclei beyond the stability valley and investigate structure peculiarities of superheavy and exotic nuclei; to study dynamics of nuclear collisions at low and intermediate energies accompanied by production of stable as well as radioactive nuclides; to investigate fundamental properties of various few-body systems and develop rigorous and effective mathematical methods of calculations of their properties; to explore the dynamics of particle-nucleus and nucleus-nucleus collisions at relativistic energies and nuclear matter properties and its phase transitions at extreme values of temperature and density. 

Expected main results in 2018:

  • Calculation of electron capture cross sections and rates for hot neutron-rich nuclei within the thermal quasiparticle RPA with Skyrme forces. 

    Development of a general scheme to extract spurious admixtures in self-consistent calculations for electric and magnetic nuclear excitations.

  • Inclusion of viscosity effects at the hydrodynamic stage of the system evolution within the hybrid model, HydHSD, joining the initial fast stage, described by the hadron string dynamics (HSD) model, and subsequent hydrodynamical expansion. Calculation of the rapidity distributions as well as transverse momentum spectra of identified hadrons (including strange particles), produced in the NICA energy range.

    Search for the analytical solutions for the transverse momentum distributions of the massive particles given in the framework of the nonextensive statistics.
