Using a Li-6 nucleus beam extracted from the JINR Synchrophasotron at momentum 2.67A GeV/c a secondary beam was produced with a composition of 1% of He-6 and 99% of H-3 nuclei. Preliminary results on the features of nucleus-nucleus interactions of He-6 nuclei and charge exchange (CE) of H-3 nucleus are presented. Interactions of He-6 nucleus external neutrons with emulsion nuclei as well as a coherent stripping of He-6 nucleus external neutrons are observed. A mean range of H-3 nuclei to inelastic interactions in the BR-2 type emulsion is equal to 23.±3.0 cm. A mean range in emulsion for a nuclear CE process H-3 to He-3 is equal to 40±16 m. The CE cross-sections with a charged meson production or without it are approximately equal. The CE cross-section with excitation of a target nucleus exceeds the one without excitation. The mean transverse momentum of He-3 nuclei is equal to 0.16±0.03 GeV/c.
