The isospin symmetry plays a key role in nuclear systems. In atomic nuclei, however, the presence of the Coulomb interaction breaks this symmetry, inducing a mixing between states with different isospin values. I will report the study the isospin symmetry breaking in the compound nucleus ${}^{60}Zn$, based on the analysis of the $\gamma$-ray emission of the Giant Dipole Resonance in the fusion reactions {{}^{32}S}+${}^{28}Si$. The experiment was performed in Laboratori Nazionali di Legnaro using an array of HPGe detectors (GALILEO) coupled with: ten $LaBr_{3}$:Ce for $\gamma$-ray detection, an array of silicon detectors (EUCLIDES) for charge particle detection and an array of BC501A scintillators (NeutronWall) for neutron detection. The status of the analysis will be reported.
