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 will be 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 95MeV beam energy has been measured at LNL using the GARFIELD+Ring Counter(RCo) apparatuses. The comparison of highly exclusive data to statistical model calculations allows us to give constraints on the nuclear level density for light systems and to put in evidence out-of-equilibrium effects - tentatively interpreted as alpha-clustering effects, both in the entrance channel of the reaction and in the dissipative dynamics on the path towards thermalisation.
