| 英文摘要 | Elliptic flow (v(2)) and hexadecupole flow (v(4)) of light clusters have been studied in detail for 25 MeV/nucleon (86)Kr + (124)Sn at large impact parameters by using a quantum molecular dynamics model with different potential parameters. Four sets of parameters including soft or hard equation of state (EOS) with or without symmetry energy term are used. Both number-of-nucleon (A) scaling of the elliptic flow versus transverse momentum (pt) and the scaling of v(4)/A(2) versus (pt/A)(2) have been demonstrated for the light clusters in all above calculation conditions. It is also found that the ratio of v(4)/A(2) maintains a constant of 1/2 which is independent of pt for all the light fragments. Comparisons among different combinations of the EOS and the symmetry potential term show that the above scaling behaviours are sound and independent of the details of potential, while the strengths of flows are sensitive to the EOS and the symmetry potential term. |
