A Comparison Study of Collisions at Relativistic Energies Involving Light Nuclei

We present extensive comparisons of 16O+16O collisions at a center-of-mass energy per nucleon pair sNN=200 GeV and 208Pb+16O collisions at sNN=68.5 GeV as well as 20Ne+20Ne collisions at sNN=200 GeV and 208Pb+20Ne collisions at sNN=68.5 GeV based on a multiphase transport (AMPT) model. We recommend measuring the ratio of the elliptic flow to the triangular flow, which shows appreciable sensitivity to the structure of light nuclei, as also found in other studies. This is especially so if the observable is measured near the target rapidity in 208Pb+16O or 208Pb+20Ne collisions, as originally found in the present study. Our study serves as a useful reference for understanding the effect of structure on observables in collisions involving light nuclei under analysis or on the schedule.
