Abstract
The existence of cluster structures in 10Be and 16C neutron-rich isotopes is investigated via projectile break-up reactions induced on polyethylene (CH2) target. We used a fragmentation beam constituted by 55MeV/u 10Be and 49MeV/u 16C beams provided by the FRIBs facility at INFN-LNS. Invariant mass spectra of 4He+6He and 6He+10Be breakup fragments are reconstructed by means of the CHIMERA 4π detector to investigate the presence of excited states of projectile nuclei characterized by cluster structure. In the first case, we suggest the presence of a new state in 10Be at 13.5MeV. A non-vanishing yield corresponding to 20.6MeV excitation energy of 16C was observed in the 6He+10Be cluster decay channel. To improve the results of the present analysis, a new experiment has been performed recently, taking advantage of the coupling of CHIMERA and FARCOS. In the paper we describe the data reduction process of the new experiment together with preliminary results.
