Fragmentation reactions, typically performed at energies ~E/A > 50 MeV, produce neutron-rich nuclei but leave little angular momentum in the residues. In this work we have examined the product distribution and angular momentum input for a 12C beam at 30 MeV/A on a thick (40 mg/cm2) target of 51V, testing the feasibility of in-beam gamma-ray spectroscopy study of target fragments at this lower energy. This technique allows the study of some neutron-rich nuclei to moderate spins, complementing the beam fragmentation studies.
