Abstract

A search for the neutron-unbound nucleus ²¹C was performed via the single-proton removal reaction from a beam of ²²N at 68 MeV/u. Neutrons were detected with the Modular Neutron Array (MoNA) in coincidence with ²⁰C fragments. No evidence for a low-lying state was found, and the reconstructed C20+n decay-energy spectrum could be described with an s-wave line shape with a scattering length limit of |_{a s}| < 2.8fm, consistent with shell-model predictions. A comparison with a renormalized zero-range three-body model suggests that ²²C is bound by less than 70 keV.
