Abstract

The initial geometry effect on collective flows, which are inherited from initial projectile structure, is studied in relativistic heavy-ion collisions of ¹²C+¹⁹⁷Au by using a multiphase transport model (AMPT). Elliptic flow (v₂) and triangular flow (v₃) which are significantly resulted from the chain and triangle structure of ¹²C with three-\ensuremathα clusters, respectively, in central ¹²C+¹⁹⁷Au collisions are compared with the flow from the Woods-Saxon distribution of nucleons in ¹²C. v₃/v₂ is proposed as a probe to distinguish the pattern of \ensuremathα-clustered ¹²C. This study demonstrates that the initial geometry of the collision zone inherited from nuclear structure can be explored by collective flow at the final stage in heavy-ion collisions.
