Abstract:

Nuclei far away from the valley of stability are actively studied at experimental and theoretical levels. A nuclear model able to treat drip-line nuclei consistently is the Gamow Shell model (GSM). GSM is a configuration interaction model based on the use of the one-body Berggren basis. The Berggren basis contains bound, resonance and scattering states, so that continuum coupling is present at basis level. Inter-nucleon correlations are taken into account via the use of configuration mixing, so that both structure and reaction degrees of freedom are included in GSM.

Unbound systems bearing A=3-5 nucleons could be precisely studied in a GSM no-core approach. An effective interaction has been fitted in a core + valence nucleon picture using GSM for light nuclei, where the statistical errors of fitted parameters have been assessed. Spectra, nucleon densities, and correlations densities have been evaluated therein. Scattering and radiative capture cross sections calculated with GSM will also be presented in this context.
