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 mb. The distributions of the fragment transverse momenta projected onto the emulsion plane are used to obtain the nucleon Fermi momentum of 6Li, PF, this value being equal to MeV/c. The high momentum component in the transverse momentum distributions of 3He and 4He isotopes is observed.
