| 摘 要： | 基于同位旋和动量依赖的强子输运模型IBUU04，研究了132Sn+124Sn在三种不同碰撞能量、两种不同对称能作用下，中-质微分流随快度的变化关系. 发现中-质微分流的强度随碰撞能量的增大而增强. 在碰撞能量为400 MeV每核子时，中-质微分流对对称能最为敏感. 关键词：重离子碰撞中-质微分流对称能

| Abstract: | Based on the isospin-and momentum-dependent transport model IBUU04,we investigated the neutron-proton differential flow in the 132Sn+ 124Sn mid-central collisions at beam energies of 400MeV/A,600MeV/A and 800MeV/A by adopting two different symmetry energies.It was found that the neutron-proton differential flow as a function of rapidity is very sensitive to the density dependence of symmetry energy,especially at incident energies around 400MeV/A. |

| Keywords: | heavy ion collisions neutron-proton differential flow symmetry energy |
