摘要：
In these proceedings, we present the measurements of centrality, transverse momentum, and rapidity dependences of proton (p) and light-nuclei (d ((d) over bar), t, He-3 ((He-3) over bar), and He-4) production in Au+Au collisions at root s(NN) = 3 GeV, and isobaric (Ru+Ru and Zr+Zr) collisions at root s(NN) = 200 GeV. The compound yield ratios in central collisions at 3 GeV are found to be larger than the transport model calculations. Furthermore, the kinetic freeze-out parameters at 3 GeV show a different trend compared to those of light hadrons (pi, K, p) at higher energies.
