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

摘要

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