Abstract The in-plane and out-of-plane emissions of light charged particles and intermediate mass fragments were measured for ⁴⁰Ar + ¹⁵⁹Tb collisions at 30 MeV/nucleon. An in-plane enhancement was observed for mid-rapidity light particles and fragments, indicating that a rotational effect exists in this reaction system. This enhancement increased with mass for light particles with Z≤2, but became nearly constant values for fragments with Z≥3. This enhancement was observed to increase strongly with increasing impact parameter.
