Particle-gamma coincidences with Agata+Euclides for study of light-ion fusion at astrophysical energies

The study of light ion fusion at sub-barrier energies has a crucial role in astrophysics because they determine the dynamics of stellar evolution. In particular, the discovery of fusion hindrance in these systems increased the interest in their study because this phenomen appears as a smaller cross-section than expected by theoretical calculations and this affects the abundances of many isotopes. In this thesis, it is described the data analysis of a text experiment performed on the reaction 30Si+12C where fusion hindrance was already observed in the past. The purpose of the test was to demostrate the feasibility of cross-section measurements in the nano-barn range using the particle-gamma coincidences technique exploiting the Agata+Euclides setup. With this technique the cross-section is obtained by counting the coincidences between the charged particles evaporated from the compund nucleus and the gamma-rays emitted by the evaporation residues.
