Pre-equilibrium emission and clustering in medium-mass nuclei: Ti-46 from O-16+Si-30, O-18+Si-28, F-19+Al-27

The study of nuclear cluster states bound by valence neutrons is a field of recent large interest. In particular, it is interesting to study the pre-formation of a-clusters in alpha-conjugate nuclei and the dynamical condensation of clusters during nuclear reactions. The NUCL-EX collaboration (INFN, Italy) is carrying out a research campaign studying pre-equilibrium emission of light charged particles and cluster properties of light and medium-mass nuclei. For this purpose, a comparative study of the three nuclear reactions: O-16 + Si-30, O-18 + Si-28 and F-19 + Al-27, has been recently carried out using the GARFIELD+RCo 4 pi setup. After a general introduction on the experimental campaign, the preliminary results for the three systems are presented.
