The Isospin mixing phenomenon was measured by the study of the Isovector Giant Dipole Resonance (IVGDR) in ${}^{60}Zn$ and ${}^{62}Zn$ at two different excitation energies $E^{*} = 47$ MeV and $E^{*} = 58$ MeV. A fusion evaporation reaction, with a beam of ${}^{62}S$ and two targets of ${}^{28}Si$ and ${}^{30}Si$, was used to produce ${}^{60}Zn$ and ${}^{62}Zn$ respectively. The second reaction was used as a reference. The experimental setup was composed of a GALILEO array (germanium detectors) coupled to the large-volume $LaBr_{3}(Ce)$ detectors for the $\gamma$-rays measuring. An overview on the ongoing analysis and on preliminary results is presented.
