The structure of the neutron-rich carbon isotopes 16,17,19C has been investigated using one-neutron knockout reactions on a 9Be target at approximately 60 MeV/nucleon. Partial cross sections and associated momentum distributions corresponding to final states of the 15,16,18C 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 17,19C are 3 / 2+ and 1 / 2+, respectively. It is suggested that the accepted one-neutron separation energy for the ground state of 19C needs to be revised upwards.
