Study of cluster structures in 10Be and 16C neutron-rich nuclei via break-up reactions

Projectile break-up reactions induced on polyethylene (CH2) target are used in order to study the spectroscopy of 10Be and 16C nuclei. Forthe present experiment we used 10Be and 16C beams delivered by theFRIBs facility at INFN-LNS, and the CHIMERA 4π multi-detector.10Be and 16C structures are studied via a relative energy analysis of break-up fragments. The 4He+6He break-up channel allowed us tostudy the spectroscopy of 10Be; in particular we find evidence of a new state in 10Be at 13.5 MeV excitation energy. The 16C nucleus isstudied via 6He-10Be correlation; we find the fingerprint of a possible state at about 20.6 MeV.

Projectile break-up reactions induced on polyethylene (CH2) target are used in order to study the spectroscopy of Be-10 and C-16 nuclei. For the present experiment we used Be-10 and C-16 beams delivered by the FRIBs facility at INFN-LNS, and the CHIMERA 4 pi multi-detector. Be-10 and C-16 structures are studied via a relative energy analysis of break-up fragments. The He-4+He-6 break-up channel allowed us to study the spectroscopy of Be-10; in particular we find evidence of a new state in Be-10 at 13.5 MeV excitation energy. The C-16 nucleus is studied via He-6-Be-10 correlation; we find the fingerprint of a possible state at about 20.6 MeV.
