Abstract

The results from an experimental search for the production of heavy lithium isotopes 11,12Li in stopped π−-meson absorption reactions on a 14C radioactive target are presented. A pronounced peak is observed in the missing mass spectrum of the 14C(π−, pp)X reaction, which is associated with the formation of a nucleon-unstable 12Li state with the following resonance parameters: E R = 4.0 ± 0.2 MeV and Γ = 1.1 ± 0.2 MeV. Resonance parameters of three low-lying 11Li excited states were determined in the 14C(π−, pd)X, reaction.
