Results are presented of measurement of the velocity spectra and angular distributions of secondary particles emitted during the collision of alpha-particles with energies of 3.6 GeV/nucleon with lead nuclei. A maximum in the angular distribution for velocities —0.5 sec may be explained by a model of a shock wave propagating in the nuclear material.
