Abstract（摘要）:

The Gamow shell model has become a well established method to implement halo and resonance nuclei of complex structure. It is a configuration interaction model, where one-body basis states are issued from the Berggren basis, comprising bound, resonance and scattering states. As continuum coupling is included at basis level, with inter-nucleon correlations taken into account through configuration mixing, the Gamow shell model is the tool of choice to describe many-body halo and resonance nuclei. After introductory calculations done with schematic interactions involving a few valence nucleons, the Gamow shell model is now routinely applied to realistic situations. We will then present recent applications of the Gamow shell model, which are related to current experiments involving dripline nuclei.Calculations of the isotopic chains of hydrogen, lithium and oxygen isotopes, modelled with effective interactions in the core + valence picture, will be illustrated. Recent applications involving proton-rich nuclei of experimental interest will also be dealt with in that framework. One will show calculations of A=4 nuclear many-body states done in the frame of the no-core Gamow shell model, where the isospin symmetry breaking present in broad resonances will be emphasized.
