Impact parameter dependence of the scaling of anisotropic flows in intermediate energy heavy-ion collisions

The scaling behaviors of anisotropic flows of light charged particles are studied for 25 MeV/u 40Ca＋40Ca collisions at different impact parameters by the isospin-dependent quantum molecular dynamics model. The nucleon- number scaling of elliptic flow exists and the scaling of the ratios of v4/v2 2 a...

Summary:The scaling behaviors of anisotropic flows of light charged particles are studied for 25 MeV/u 40Ca＋40Ca collisions at different impact parameters by the isospin-dependent quantum molecular dynamics model. The nucleon- number scaling of elliptic flow exists and the scaling of the ratios of v4/v2 2 and v3/（v1v2） is applicable to collisions at almost all impact parameters except for peripheral collisions.
