The spectroscopy of 10Be and 16C isotopes is studied via projectile break-up reactions induced on polyethylene (CH2) target, by using a 55 MeV/u 10Be and a 49 MeV/u 16C beams provided by the FRIBs facility at INFN-LNS. We reconstruct the 10Be and 16C relative energy spectra to evince the presence of excited states characterized by cluster structure. By inspecting the 4He+6He relative energy spectrum we find evidence of a new possible state of 10Be at 13:5 MeV for which the corresponding angular correlation indicates a hypothetical 6+ assignment. Finally, from binary (6He+10Be) cluster decomposition of 16C we show the indication of a possible new state at about 20.6 MeV.

Abstract
The spectroscopy of 10Be and 16C isotopes is studied via projectile break-up reactions induced on polyethylene (CH2) target, by using a 55 MeV/u 10Be and a 49 MeV/u 16C beams provided by the FRIBs facility at INFN-LNS. We reconstruct the 10Be and 16C relative energy spectra to evince the presence of excited states characterized by cluster structure. By inspecting the 4He+6He relative energy spectrum we find evidence of a new possible state of 10Be at 13:5 MeV for which the corresponding angular correlation indicates a hypothetical 6+ assignment. Finally, from binary (6He+10Be) cluster decomposition of 16C we show the indication of a possible new state at about 20.6 MeV.| File | Dimensione | Formato | |
