The effective hamiltonian and spectra of the Op shell

The scientific legacy of J.P. Elliott

“…Although sensible results were obtained when the density of the nucleus was constrained at the known value, it was found that the Sussex interaction did not have the correct saturation properties to produce this value as the equilibrium density [45]. In the subsequent years Phil Elliott and collaborators proposed modified versions of the Sussex interaction by in-corporating effects of a hard core [46,47,48] or, alternatively, by considering the addition of a density-dependent term [49,50,51]. The reader should not be under the impression that each of these papers presents 'just' another application or extension of the Sussex interaction.…”
