Abstract

The unbound isotopes ¹⁰Li, ¹²Li and ¹³Li have been observed after nucleon-knockout reactions at relativistic energies with ¹¹Li and ¹⁴Be beams impinging on a liquid hydrogen target. The channels ⁹Li + n, ¹¹Li + n and ¹¹Li + 2 n were analysed in the ALADIN-LAND setup at GSI. The ¹⁰Li data confirm earlier findings, while the ¹²Li and ¹³Li nuclei were observed for the first time. The ¹¹Li + n relative-energy spectrum shows that the ground state of ¹²Li can be described as a virtual s-state with a scattering length of -13.7(1.6) fm. A broad energy spectrum was found for the ¹¹Li + 2 n channel. Based on the assumption that the relative-energy spectrum is dominated by a correlated background presumably stemming from initial correlations in the ¹⁴Be ground-state, evidence for a ¹³Li resonance at 1.47(31) MeV above the ¹¹Li + 2 n threshold with a width around 2 MeV has been found.
