Be10 and C16 spectroscopy has been investigated by analyzing their breakup events on CH2 and CD2 targets. Breakup fragments have been detected by means of the CHIMERA detector. In particular, we investigated cluster decays of Be10 in He4+He6 and of C16 in He6+Be10 and He4+He6+He6. From the relative energy analysis of breakup fragments, we investigate the spectroscopy of excited states of projectile nuclei. In the Be10 case we observe known states at 9.51, 10.16, 10.6, and 11.8 MeV. Further, we suggest the existence of a new state at 13.5 MeV, possibly 6+ as indicated from angular correlation analysis. The relative energy (Erel+Eth) spectrum of C16, reconstructed starting from He6+Be10 correlations, shows a peak at about 20.6 MeV, probably related to the existence of an high-lying excited state. Non-vanishing yields are also seen in the triple coincidences He4+He6+He6.
