Abstract
The structure of the neutron-rich carbon isotopes has been investigated using one-neutron knockout reactions on a target at approximately 60 MeV/nucleon. Partial cross sections and associated momentum distributions corresponding to final states of the residues were measured and compared with predictions based on a shell-model theory and an eikonal model of the reaction mechanism. Spectroscopic factors and l-value assignments are given. The ground-state spins of are and respectively. It is suggested that the accepted one-neutron separation energy for the ground state of needs to be revised upwards.
