The separation energy and half-life of some heavy proton emitting nuclei, and the single-particle structure of the unbound 11-N, have been evaluated by implementing a careful numerical treatment to solve Schrodinger equation in a continuum discretization context. The basic scheme behind the method consists in using the ground-state proton emitter in connection with an isolated single-particle resonance.
The structure of the isovector dipole resonance in neutron-rich calcium isotope, $^{60}Ca$, has been investigated by implementing a careful treatment of the differences of neutron and proton radii in the continuum random phase approximation ($RPA$). The calculations have taken into account the current estimates of the neutron skin. The estimates of the escape widths for direct neutron decay from the pygmy dipole resonance ($PDR$) were shown rather wide, implicating a strong coupling to the continuum. The width of the giant dipole resonance ($GDR$) was evaluated, bringing on a detailed discussion about its microscopic structure.
The stability of the 11Li exotic nucleus is discussed focusing on the existence of single particle positive energy components in its ground state structure. The existence of these continuum components is an outcome of many models using the available experimental data of 10Li. We show that if this were the case, the 11Li main decay mode could not be the beta decay.
