| English Abstract | The alpha-clustering configurations in light nuclei have attracted a great deal of attention over past years. Nuclear reactions serve as one possible way to study this topic. The aim of this paper was to discuss whether or not heavy-ion collisions at Fermi energy could be a good tool to investigate the cluster configurations in light nuclei. In particular, (16) O + Au-197 collisions are simulated using a transport model to check if any observable change is sensitive to the cluster configurations. Within an extended quantum molecular dynamics model, two different a-clustering configurations (chain and tetrahedron) of O-16 were employed in the initialization. O-16+ Au-197 collisions at a beam energy of 40 MeV/nucleon with an impact parameter of 3 fm were simulated; then the collective flow parameters (v(1), v(2), v(3), and v(4)) of free protons were analyzed as a function of both the rapidity and the transverse momentum. It was found that flow parameters (v(1), v(2), v(3), and v(4)) decrease with an increase of the flow order, and that the difference in the flow parameters of free protons caused by the initial a-clustering configurations increases with transverse momentum. In the higher transverse momentum region (0.2-0.25 GeV/c), these flow patterns are quite sensitive to the initial alpha-clustering configurations, and can be regarded as sufficiently sensitive probes that can be used to study the clustering configurations in light nuclei. |
