Description of odd nuclei in the Skyrme-Hartree-Fock method — •Klaus Pototzky1, Jochen Erler1, Paul-Gerhard Reinhard1, and Valentin Nesterenko21Institut für Theoretische Physik II, Universität Erlangen-Nürnberg, Erlangen, Germany — 2Bogoliubov Laboratory of Theoretical Physics, Joint Institute for Nuclear Research, Dubna, Russia

The Skyrme-Hartree-Fock method is a self-consistent nuclear mean-field model which is widely used and a reliable model for the groundstate properties of nuclei from oxygen up to superheavy elements. It has been mostly applied to even-even nuclei so far. However these represent only a quarter of all known nuclei.

Even-odd and odd-even nuclei require a different treatment, since the time-reversal symmetry of the system is broken. We use a BCS+Blocking approach to describe those nuclei. The symmetry breaking leads to non-vanishing time-odd densities. The terms in the Skyrme energy functional containing time-odd densities are not yet well explored. The effects of these terms are analysed and the results are compared with experimental data. We study the odd-even staggering of binding energies, single particle excitations of odd nuclei and magnetic modes in even nuclei.
