Abstract: We present the results of the study of interaction of the relativistic ⁶Li nucleus with the momentum 4.5 GeV/c per nucleon with the photoemulsion. Yields of the ¹H (³He) and ²H (⁴He) isotopes due to the fragmentation of ⁶Li are found to be almost equal. Cross sections for the charge exchange and pickup reactions are found to be <sigma>_exch=9±2 mb. The distributions of the fragment transverse momenta projected onto the emulsion plane are used to obtain the nucleon Fermi momentum of ⁶Li, P_F, this value being equal to 129±8 MeV/c. The high momentum component in the transverse momentum distributions of ³He and ⁴He isotopes is observed.
