Gamma decay of giant resonances by using Skyrme functionals

A microscopic model, entirely based on Skyrme energy density lunctionals, has been developed to study the γ -decay ol giant resonances. In particular, it treats the ground-state decay within the fully self-consistent Random Phase Approximation (RPA) and the decay to low-lying states at the lowest order beyond RPA. This model is applied to 208 Pb and the results are compared with experimental data and with previous theoretical results obtained, in the past decades, using phenomenological models.
