Level structure of lithium isotope 6 Li

The level structure of lithium isotope 6Li is studied in the reaction of the absorption of stopped pions 12С(π−, tt)X. States are sought up to excitation energies of ~40 MeV in the missing mass spectrum. Data on highly excited states are analyzed to determine their origins. The final results are compared to those from searches for the highly excited states of heavier lithium isotopes produced in the reaction of the absorption of stopped pions.
