In the NUCL-EX extensive research program on light charged particles pre-equilibrium emission from hot nuclei, the reactions ${}^{16}O+{}^{30}Si$, ${}^{18}O+{}^{28}Si$ and ${}^{19}F+{}^{27}Al$ at about 130 MeV have been measured at the GARFIELD+RCo array in Legnaro National Laboratories. The complete analysis is being performed on an event-by-event basis. The experimental data are compared to the theoretical predictions where events are generated by numerical codes based on pre-equilibrium and/or statistical models and then filtered through a software replica of the setup. Effects related to the entrance channel and to the colliding ions cluster nature are emphasized through differences between the predictions and the experimental data. After a general introduction on the experimental campaign, the preliminary results will be presented.
