Response function beyond mean field of neutron-rich nuclei

Abstract

The damping of single-particle and collective motion in exotic isotopes is a new topic and its study may shed light on basic problems of nuclear dynamics. For instance, it is known that nuclear structure calculations are not able, as a rule, to account completely for the empirical single-particle damping. In this contribution, we present calculations of the single-particle self-energy in the case of the neutron-rich light nucleus ${}^{28}$O, by taking proper care of the continuum, and we show that there are important differences with the case of nuclei along the valley of stability.
