Angela and the electric dipole response -- giant and pygmy, hot and cold, isoscalar and isovector

Abstract

The impact of Angela Bracco's work on the electric dipole response of nuclei is discussed using three examples of current nuclear structure problems: disentangling different contributions to the decay width of the giant dipole resonance, the equivalence of photo- absorption and emission and the nature of the pygmy dipole resonance.
