Statistical analysis methods in the search of resonances in low-energy heavy-ion reactions

The decay of resonant states, formed in low-energy heavy-ion collisions, produces structure in the excitation function and in the angular distributions. Statistical phenomena, too, call produce a similar behaviour. For this reason a statistical analysis of the experimental distributions is needed. By using this method we evidenced resonances in S-32+Ti-46, Ni-58 and Ni-62 collisions at energies just above the Coulomb barrier.
