Description of loosely bound and resonant states with Gamow expansion techniques

Recently, the shell model in the complex k-plane (the so-called Gamow Shell Model) has been formulated using a complex Berggren ensemble representing bound single-particle states, single-particle resonances, and non-resonant continuum states. The single-particle basis used is that of the Hartree-Fock potential generated self-consistently by the finite-range residual interaction. In this framework, we shall discuss energy spectra and other observables of neutron-rich oxygen, helium and lithium isotopes. It is shown that correlations due to scattering components cannot be neglected. The description of proton emitters with Gamow states expansions will also be discussed.
