摘要
In the framework of studying clustering effects in N = Z light nuclei, an experiment was carried out to get information on the properties of the Cr-48 composite nuclei produced via the Mg-24 + Mg-24 reaction. In particular, the study regards the Cr-48 at 60 MeV of excitation energy where a resonance with a narrow width (170 KeV) has been found by measuring the elastic and anelastic channels. To determine the deformation of this state, evaporative Light Charged Particles (LCP) are measured and compared to the Statistical Model (SM) predictions, which are very sensitive to nuclear deformation. The experiment was performed at LNL using the 8 pi LP apparatus to select LCPs and a Parallel Plate Avalanche Counter (PPAC) system to detect the Evaporation Residues (ER). Preliminary results on the measurements of ER - LCP and LCP - LCP angular correlations are presented which indicate the presence of a very large deformation. The analysis will proceed with the extraction of the LCP energy spectra and with the angular correlations for high multiplicity channels to determine the deformation.
