The unbound isotopes 10Li, 12Li and 13Li have been observed after nucleon-knockout reactions at relativistic energies with 11Li 14Be beams impinging on a liquid hydrogen target. channels Li9+n, Li11+n Li11+2n were analysed in the ALADIN-LAND setup GSI. 10Li data confirm earlier findings, while nuclei for first time. relative-energy spectrum shows that ground state of can be described as virtual s-state scattering length −13.7(1.6) fm. A broad energy was found channel. Based assumption is dominated by correlated background presumably stemming from initial correlations ground-state, evidence resonance 1.47(31) MeV above threshold width around 2 has found.
