Abstract

\ensuremathα-clustered structures in light nuclei could be studied through ``snapshots'' taken by relativistic heavy-ion collisions. A multiphase transport model is employed to simulate the initial structure of collision nuclei and the proceeding collisions at center of mass energy √s_NN=6.37 TeV. This initial structure can finally be reflected in the subsequent observations, such as elliptic flow (v₂), triangular flow (v₃), and quadrangular flow (v₄). Three sets of the collision systems are chosen to illustrate that the system scan is a good way to identify the exotic \ensuremathα-clustered nuclear structure: case I, ¹⁶O nucleus (with or without \ensuremathα-cluster) + ordinary nuclei (always in Woods-Saxon distribution) in most central collisions; case II, ¹⁶O nucleus (with or without \ensuremathα-cluster) + ¹⁹⁷Au nucleus collisions for centrality dependence; and case III, symmetric collision systems [namely, ¹⁰B + ¹⁰B, ¹²C + ¹²C, ¹⁶O + ¹⁶O (with or without \ensuremathα-cluster), ²⁰Ne + ²⁰Ne, and ⁴⁰Ca + ⁴⁰Ca] in most central collisions. Our calculations propose that relativistic heavy-ion collision experiments at √s_NN=6.37 TeV are promised to distinguish the tetrahedral structure of ¹⁶O from the Woods-Saxon one and shed light on the system scan projects in experiments.
