Description
Nuclei in the region of the nuclear chart between Z = 28 and 50 magic numbers show a collective behavior that can be attributed to the appearance of quadrupole shape mixing and/or coexistence. Advanced energy density functional (EDF) methods, including symmetry restorations and axial and triaxial shape mixing, are the perfect tools to study these phenomena from a microscopic point of view. In this contribution I will present recent systematic calculations performed with the Gogny EDF, comparing with the available experimental data and shell model calculations.
Furthermore, I will focus on specific examples of static and dynamic shape coexistence.
