Description
Nuclei at drip-lines bear unique properties such as halos or
resonant character at ground state level, inexistent in the
valley of stability. While the latter consists of standard
closed quantum systems, drip-line nuclei are open quantum
systems, so that models describing their properties must
include both nuclear inter-correlations and continuum
degrees of freedom. Coupled Cluster and Gamow Shell Model
theories, in both ab-initio and effective approaches, are
tools of choice for that matter as nuclear correlations are
present through configuration mixing while continuum degrees
of freedom are imparted by the use of the Berggren basis.
The latter methods, initially devised for structure
calculations, can now be utilized to study reaction
observables. Applications concern direct reactions on light
and medium nuclei.
