ANISOTROPIC FLOWS OF NUCLEAR CLUSTERS AND HARD PHOTON IN INTERMEDIATE ENERGY HEAVY ION COLLISIONS

摘要

Anisotropic flows of light nuclear clusters and hard photons are studied by nucleonic transport models in intermediate energy heavy ion collisions. The transverse momentum and rapidity dependences of the directed flow (v(1)) and elliptic flow (v(2)) are studied for light nuclear clusters and their scaling behaviors are found. The ratio of v(4)/v(2)(2) of nuclear clusters show a constant value of 1/2. Proton-neutron bremsstrahlung hard photon shows non-zero flows with the contrary sign of proton's flows.
