Fragment Flow in Nuclear Collisions

Abstract

The flow of light nuclei ($Z=1, 2$) and intermediate-mass nuclear fragments ($3\le Z<\mathrm{}10\mathrm{}$) is measured in collisions of 200-MeV/nucleon Au+Au over a large solid angle. An increase in the fragment-position and momentum-space alignment relative to the reaction plane is observed: The fragments exhibit stronger flow effects than light particles.
