In the recent years, cluster structures have been evidenced in many ground and excited states of light nuclei [1, 2]. Within the currently ongoing experimental campaign by the NUCL-EX collaboration we have measured the C-12+ C-12 and N-14+ B-10 reactions at 95 MeV and 80 MeV respectively, and compared experimental data corresponding to complete fusion of target and projectile into an excited Mg-24 nucleus to the results of a pure statistical model[3, 4]. We found clear deviations from the statstical model in the decay pattern: emission channels involving multiple alpha particles are more probable than expected from a purely statistical behavior. To continue the investigation on light systems, we have recentely measured the O-16+ C-12 reaction at three different beam energies, namely E-beam = 90, 110 and 130 MeV.

Abstract
In the recent years, cluster structures have been evidenced in many ground and excited states of light nuclei [1, 2]. Within the currently ongoing experimental campaign by the NUCL-EX collaboration we have measured the C-12+ C-12 and N-14+ B-10 reactions at 95 MeV and 80 MeV respectively, and compared experimental data corresponding to complete fusion of target and projectile into an excited Mg-24 nucleus to the results of a pure statistical model[3, 4]. We found clear deviations from the statstical model in the decay pattern: emission channels involving multiple alpha particles are more probable than expected from a purely statistical behavior. To continue the investigation on light systems, we have recentely measured the O-16+ C-12 reaction at three different beam energies, namely E-beam = 90, 110 and 130 MeV.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
