Scaling of Anisotropic Flow in Intermediate Energy Heavy Ion Collisions

  • Anisotropic flows (v2 and v4) of light nuclear clusters are studied by Isospin-Dependent Quantum Molecular Dynamics model for the system of 86Kr+124Sn at 25MeV/A and large impact parameters. Number-of-nucleon scaling of the elliptic flow (v2) is demonstrated for the light fragments up to A=4, and the ratio of v4/v22 shows a constant value of 1/2. It can be understood by the coalescence mechanism in nucleonic degree of freedom for the cluster formation.

Abstract: Anisotropic flows (v2 and v4) of light nuclear clusters are studied by Isospin-Dependent Quantum Molecular Dynamics model for the system of 86Kr+124Sn at 25MeV/A and large impact parameters. Number-of-nucleon scaling of the elliptic flow (v2) is demonstrated for the light fragments up to A=4, and the ratio of v4/v22 shows a constant value of 1/2. It can be understood by the coalescence mechanism in nucleonic degree of freedom for the cluster formation.
