Priority:

Status:

In-progress

Nuclear Theory

Leader:

V.V. Voronov

Scientific Programme:
The main goals are to investigate properties of atomic nuclei at the limits of their stability; to study dynamics of nuclear reactions and mechanisms of production of exotic nuclides; to investigate fundamental properties of exotic few-body nuclear, atomic and molecular systems; to study the behaviour of nuclear matter and its phase transitions at high temperature and density; to evaluate new methods of relativistic nuclear physics and apply them to analyze subnuclear and spin effects in few-nucleon systems.

Expected main results in 2007:

Study of the influence of an effective interaction in the particle-particle channel on anharmonic corrections in neutron-rich Sn isotopes within the self-consistent approach based on the finite rank separable approximation with Skyrme forces.

Incorporation of nuclear superfluidity effects in the method of Wigner function moments.

Analysis of the role of isovector and isoscalar effective masses as well as time-odd densities in deformed nuclei in the framework of the self-consistent RPA approach with Skyrme interactions.

Calculation of a strength distribution of electromagnetic transitions exciting isomers in deformed nuclei.
Investigation of dependence of an effective nucleon-nucleon interaction on pseudospin basing on the mean field potential derived in the QCD framework.

Calculation of a production rate of new isotopes ^220-227Pu and ^230,231Cm in complete fusion reactions and determination of the optimal conditions for the maximum production cross-section.

Calculation of the yield of neutron-rich isotopes of Ca, Ti, Kr, Sn, and Xe in multinucleon transfer reactions.

Investigation of a mechanism of changing the parity splitting sign in alternating parity bands at high angular momentum.
Study of specific properties of halo-nuclei and exotic atoms.

Development of the method to treat effects of a center-of-mass motion in atomic scattering in a harmonic trap.

Derivation of optimal estimations for perturbation of the spectra and spectral subspaces.
Analysis of angular and energy correlations of three fragments at the final stage of break-up reactions to perform a continuum spectroscopy of two-neutron halo-nuclei.

Analysis of experimental differential cross-sections of a proton elastic scattering off ⁶He with the proposed microscopic optical potential to estimate the sensitivity of theoretical results to model assumptions on the ⁶He structure.

Study of the parity non-conservation in nuclear processes with highly intensive and/or highly polarized photon beams.

Derivation of a thermodynamically consistent equation of state for hot and dense nuclear matter in the framework of the relativistic mean-field theory with hadron masses and coupling constants depending on the sigma-field.
