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 Ca-40+Ca-40 collisions at different impact parameters by the isospin-dependent quantum molecular dynamics model. The nucleonnumber scaling of elliptic flow exists and the scaling of the ratios of v(4)/v(2)(2) and v(3)/(v(1)v(2)) is applicable to collisions at almost all impact parameters except for peripheral collisions.
