Transverse radius dependence for transverse velocity and elliptic flow in intermediate energy HIC

Transverse radius dependence for transverse velocity and elliptic flow in intermediate energy HIC

导出

摘要 The mean transverse velocity and elliptic flow of light fragments （A≤2） as a function of transverse radius are studied for 25 MeV/nucleon 64Cu＋64Cu collisions with impact parameters 3–5 fm by the isospin- dependent quantum molecular dynamics model. By comparison between the in-plane and the out-of-plane transverse velocities, the elliptic flow dependence on the transverse radius can be understood qualitatively, and variation of the direction of the resultant force on the fragments can be investigated qualitatively.
