The experimental search for the production of heavy lithium isotopes 10-12Li was carried out in the stopped -meson absorption reactions on the radioactive target 14C. The study of 10Li was performed in the missing mass spectra in the 14C
and 14C
reactions. Three excited states of 10Li were identified. A broad state with a resonance energy
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
reaction. In the 14C
reaction an evidence for a 12Li excited state (
MeV and
MeV) was found.
