Abstract.

The experimental search for the production of heavy lithium isotopes 10-12Li was carried out in the stopped \(\pi^{-}\) -meson absorption reactions on the radioactive target 14C. The study of 10Li was performed in the missing mass spectra in the 14C \( (\pi^{-},pt)X\) and 14C \( (\pi^{-},dd)X\) reactions. Three excited states of 10Li were identified. A broad state with a resonance energy \(E_{r} = 6.13 \pm 0.11\) MeV has the highest excitation energy, compared with previously observed levels. The resonance parameters of three low-lying excited states of 11Li were determined in the 14C \( (\pi^{-}, pd)X\) reaction. In the 14C \( (\pi^{-},pp)X\) reaction an evidence for a 12Li excited state (\( E_{r} = 4.0 \pm 0.2\) MeV and \( \Gamma = 1.1 \pm 0.2\) MeV) was found.
