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 ²⁰⁸Pb and the results are compared with experimental data and with previous theoretical results obtained, in the past decades, using phenomenological models.
