Abstract
An experimental campaign has been proposed at Laboratori Nazionali di Legnaro - INFN, in order to progress in our understanding of statistical properties of light nuclei at excitation energies above particle emission thresholds. Exclusive measurements from fusion-evaporation reactions are used. Light nuclei are interesting probes for high temperature nuclear thermodynamics and the role of structure effects in their decay is a subject of great interest. A first reaction: 12C+12C at 95 MeV beam energy has been measured using the GARFIELD+Ring Counter(RCo) apparatuses. A theoretical study of the system, performed with a dedicated Monte-Carlo Hauser-Feshbach code, will be shown, together with results of the data analysis. Constraints on the nuclear level density at high excitation energy for systems ranging from ∼C to Mg are given, and out-of-equilibrium effects, possibly favoured by α-structure, are put in evidence.
