Target black fragment flows in magnesium-emulsion collisions at 4.5A GeV/c

The experimental results of polar, azimuthal, and projected angular distributions of target black fragments produced in magnesium-emulsion collisions at 4.5A GeV/c (the Dubna synchrophasotron momentum) are reported. The flow characteristics are obtained. The azimuthal and projected angular distributions as well as some relationships between flows and angles depend on the size of target in the case of considering both light and heavy targets, and do not depend on the multiplicity in the case of considering heavy target.
