【 摘 要 】

We describe the results of a new experiment aimed to investigate the possible existence of cluster structures in10Be and16C isotopes. They have been investigated at the FRIBs facility of INFN-LNS by means of an invariant mass analysis on correlated projectile breakup fragments carried out with the CHIMERA 4π detector. From the analysis of the6He+4He channel we found evidence of a new state in10Be at 13.5MeV excitation energy. Concerning16C, we investigated6He+10Be correlated fragments and we found a non-vanishing yield at about 20.5MeV in the corresponding excitation energy spectrum. Finally, we describe few details of a new experiment performed at the FRIBs facility where the CHIMERA detector was coupled to the FARCOS hodoscope, with the aim to improve the presently obtained results.
