Impact parameter dependence of the scaling of anisotropic flows in intermediate energy HIC

Abstract

The scaling behaviors of anisotropic flows of light charged particles are studied for 25 \,MeV/nucleon ${}^{40}$Ca+${}^{40}$Ca collisions at different impact parameters by the isospin-dependent quantum molecular dynamics model. The number of nucleons scaling of elliptic flow is existed and the scaling of the ratios of $v_4/v_2^2$ and $v_3/(v_1{v}_2)$ are applicable for collisions at almost all impact parameters except for peripheral collisions.
