Experimental search for highly excited states of the lithium isotopes 7-9Li was carried out in the stopped -meson absorption reactions. Several states were found for the first time. Evidence of the existence of the 8Li level with
MeV,
MeV and
MeV was found in the 12C(
)X reaction. In the 11B(
)X reaction the level of 9Li with
MeV, which lies above the threshold 9Li*
6He
, was observed. An indication for the formation of the 9Li state with
MeV was obtained in the 12C(
)X reaction.
