Agrupamiento de núcleos ligeros y sus efectos en la fusión y procesos de pre-equilibrio (original) (raw)

The study of heavy ion nuclear reactionis an important tool to observe and disentangle different and competing mechanisms, which may arise in the different energy regimes. In particular, at relatively low bombarding energy, it is quite interesting the comparison between pre-equilibrium and thermal emission of light charged particles from hot nuclear systems [ 1 - 6 ]. Indeed, the nuclear structure of the interacting partners can be strongly correlated to the dynamics, especially at energies close to the Coulomb barrier, and this effect emerges when some nucleons or clusters of nucleons are either emitted or captured. In particular, a major attention has been devoted, in the last years, to the possible observation of cluster structure effects in the competing nuclear reaction mechanisms, especially when fast processes are involved. At this purpose, the four reactions 16 O+ 30 Si at 111 MeV, 16 O+ 30 Si at 128 MeV, 18 O+ 28 Si at 126 MeV, 19 F+ 27 Al at 133 MeV have been measured to s...
