Collectivity of the low-lying dipole strength in relativistic random phase approximation

Nuclear Theory 2009-11-07 v1

Abstract

The relativistic random phase approximation is applied in the analysis of the evolution of the isovector dipole response in nuclei with a large neutron excess. The self-consistent framework of relativistic mean-field theory, which has been very successfully applied in the description of ground-state properties of nuclei far from the valley of β\beta-stability, is extended to study the possible onset of low-energy collective isovector dipole modes in nuclei with extreme isospin values.
