Abstract

The present manuscript shows the importance of studying the isovector giant dipole resonance (IVGDR) to obtain information about the isospin-symmetry breaking and the shape evolution in excited nuclei. The decay of the IVGDR was measured in the compound nuclei ⁸⁰Zr and ⁸¹Rb formed at an excitation energy of MeV and . The reactions ⁴⁰Ca+⁴⁰Ca( MeV) and ³⁷Cl+⁴⁴Ca( MeV) were used to form the nuclei ⁸⁰Zr and ⁸¹Rb, respectively. The experimental setup used for the -rays detection was composed by the AGATA Demonstrator array coupled with large volume LaBr₃:Ce detectors of the HECTOR⁺ array.
