Self-consistent mean-field description of nuclear structure and dynamics—a status report

This contribution deals with the predictive power of the Skyrme-Hartree-Fock model. First, we discuss the phenomenological adjustment of the Skyrme energy-functional and the choice of proper fit data. Then, we check the reliability in extrapolations to other observables and nuclei, using two strategies: first, comparison with data for observables not included in the fit, and second, an estimate of the extrapolation error by virtue of the least-squares fitting techniques. Test cases will be energies of extremely neutron rich Sn isotopes as well as energies, giant resonances, and fission properties of super-heavy elements.
