摘要：
We present the results of the study of interaction of the relativistic Li-6 nucleus with the momentum 4.5 GeV/c per nucleon with the photoemulsion. Yields of the H-1 (He-3) and H-2 (He-4) isotopes due to the fragmentation of Li-6 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 Li-6, P-F, this value being equal to 129 +/- 8 MeV/c. The high momentum component in the transverse momentum distributions of He-3 and He-4 isotopes is observed.
