Investigation of the isovector giant dipole resonance in excited nuclei

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 γ decay of the IVGDR was measured in the compound nuclei 80Zr and 81Rb formed at an excitation energy of E∗ = 54 MeV and ≈ 20. The reactions 40Ca + 40Ca (E beam = 136 MeV) and 37Cl + 44Ca (E beam = 95 MeV) were used to form the nuclei 80Zr and 81Rb, respectively. The experimental setup used for the γ-rays detection was composed by the AGATA Demonstrator array coupled with large volume LaBr3:Ce detectors of the HECTOR+ array
