Based on the coalescence model for light nuclei production, we show that the yield ratio $\mathcal{O}_\text{p-d-t} = N_{^3\text{H}} N_p / N_\text{d}^2$ of $p$, d, and $^3$H in heavy-ion collisions is sensitive to the neutron relative…

This research use the AMPT model in Au+Au collisions to study the influence of the three nucleons correlation $C_{n^2p}$ on the light nuclei yield ratios. It is found that neglecting $C_{n^2p}$ leads to an overestimated relative neutron…

The yields and ratios of light nuclei in heavy-ion collisions offer a method to distinguish between the thermal and coalescence models. Ratios such as $\rm N_t \times N_p/N_d^2$ and $\rm N_{^3He} \times N_p/N_d^2$ are suggested as potential…
