Abstract
and spectroscopy has been investigated by analyzing their breakup events on and targets. Breakup fragments have been detected by means of the CHIMERA detector. In particular, we investigated cluster decays of in and of in and . From the relative energy analysis of breakup fragments, we investigate the spectroscopy of excited states of projectile nuclei. In the 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 as indicated from angular correlation analysis. The relative energy spectrum of , reconstructed starting from 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 .
