The nuclear compound yield ratio (\\(N_t\\)\\(\\times\\)\\(N_p\\)/\\(N_d^2\\)), which is predicted to be sensitive to the fluctuation of local neutron density, is observed to decrease monotonically with increasing charged-particle multiplicity (dN\\(_{ch}\\)/d\\(\\eta\\)) and follows a scaling behavior. The dN\\(_{ch}\\)/d\\(\\eta\\) dependence of the yield ratio is compared to calculations from coalescence and thermal models. Enhancements in the yield ratios relative to the coalescence baseline are observed in the 0%-10% most central collisions at 19.6 and 27 GeV, with a significance of 2.3$\\sigma$ and 3.4$\\sigma$, respectively, giving a combined significance of 4.1$\\sigma$. The enhancements are not observed in peripheral collisions or model calculations without critical fluctuation, and decreases with a smaller $p_{T}$ acceptance. The physics implications of these results on the QCD phase structure and the production mechanism of light nuclei in heavy-ion collisions are discussed.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.133992.v1/t1","@type":"Dataset","description":"Invariant yields of tritons at 7.7 GeV, all centralities.
