Moving away from stable nuclei
by adding either protons or neutrons, one finally reaches the
particle drip lines.
The neutron-rich, weakly-bound
nuclei close to the
neutron drip line have very unusual properties:
they are large, diffused, and superfluid [1].
The main objective of this talk is to
discuss some of the theoretical
challenges and opportunities for high-spin studies
of neutron-rich nuclei provided by radioactive nuclear beams.
The systematic behavior of rotational bands in deformed neutron-rich nuclei is investigated with the cranked Skyrme-Hartree-Fock approach and the deformed shell model. In particular, rotational properties and isovector deformations of heavy Ne and Mg isotopes are studied together with quasi-particle spectra of heavy Er isotopes. The effect of the increased surface diffuseness gives rise to the change in the position of the high-jintruder shell, and this has a significant effect on nuclear rotation.
