[en] Multiplicity, momentum and angular dependencies of charged and neutral particles in interactions of light nuclei with carbon and tantalum nuclei at at P=4.2 GeV/c per nucleon were studied with the use of propane bubble chamber. It was shown that the average multiplicity grows with the increasing of projectile nucleus mass. It was established that experimental data are well described by the cascade model. Processes of baryon clusters production in inelastic nucleus-nucleus collisions were studied. It was shown that baryon clusters are characterized by universal properties on two relativistic invariant variables b_k and x_k in the considered energy range. (author)
