New experimental investigation of the structure of Be-10 and C-16 by means of intermediate-energy sequential breakup

10Be and 16C 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 clusterdecays of 10Be in 4He+6He and of 16C in 6He+10Be and 4He+6He+6He. From the relative energy analysisof breakup fragments, we investigate the spectroscopy of excited states of projectile nuclei. In the 10Be case weobserve known states at 9.51, 10.16, 10.6, and 11.8 MeV. Further, we suggest the existence of a new state at13.5 MeV, possibly 6+ as indicated from angular correlation analysis. The relative energy (Erel + Eth) spectrumof 16C, reconstructed starting from 6He+10Be correlations, shows a peak at about 20.6 MeV, probably relatedto the existence of an high-lying excited state. Non-vanishing yields are also seen in the triple coincidences4He+6He+6He.

Be-10 and C-16 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 Be-10 in He-4 + He-6 and of C-16 in He-6 + Be-10 and He-4 + He-6 + He-6. From the relative energy analysis of breakup fragments, we investigate the spectroscopy of excited states of projectile nuclei. In the Be-10 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 (E-rel + E-th) spectrum of C-16, reconstructed starting from He-6 + Be-10 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 He-4 + He-6 + He-6.
