The neutron decay of [sup 10]Li, produced in the reaction of 80 MeV/nucleon [sup 18]O + [sup nat]C, was studied by the coincidence detection of neutrons and [sup 9]Li nuclei in a collinear geometry. An analysis of the relative velocity spectrum indicates the presence of a [sup 10]Li state which decays by very low energy neutron emission. This state corresponds to either the ground state of [sup 10]Li, in which case it is probably an [ital s]-wave resonance, or an excited state at [ital E][sub [ital x]][approx]2.5 MeV.
