Equilibrium Emission

The study of the emitted particles, comparing pre-equilibrium and thermal components, is a useful tool to examine the nuclear structure of emitters. Possible clustering effects, which may change the expected decay chain probability, could be highlighted on the competition between different reaction mechanisms. The NUCL-EX collaboration (INFN, Italy) has carried out an extensive research campaign on pre-equilibrium emission of light charged particles from hot nuclei. In this framework, the reactions 16O+30Si, 18O+28Si, 19F+27Al at 7 AMeV and 16O+30Si at 8 AMeV have been carried out using the GARFIELD+RCo array at Legnaro National Laboratories. Some anomalies in the α-particle emission channels have been evidenced in the measurement reported above, showing in an exclusive way the observed effects related to the entrance channels. The experimental results are compared to model prediction, for which the same filtering and complete event selection have been applied.

We study the 16 O +58 Ni deep inelastic reaction by using coincident charged techniques. Inclusive as well as exclusive data of the C , N , and O fully-damped fragments and their associated light charged particles ( p , d , t , and α-particles) have been collected at the IReS Strasbourg VIVITRON Tandem facility. The velocity distributions of the emitted protons and the associated multiplicity polar plots are analyzed by means of a model which describes simultaneously the nonequilibrium and the evaporative (equilibrated) components of a deep inelastic reaction mechanism. Estimates on polarization phenomena as well as the associated "decay times" of the reaction have been obtained. The hypothesis of a new "fan effect" is proposed for the proton sequential emission in the deep inelastic scattering of 16 O +58 Ni at 8.25 MeV/nucleon.
