Based on nucleons (, ) and hyperons (, ) formed at kinetic freeze-out from a quark combination model, we systematically study the production of light nuclei and hyper-nuclei in the hadronic coalescence picture. We present the analytical formula of the nucleus momentum distribution of two-body coalescence and that of three-body coalescence. We explain the experimental data of the transverse momentum spectra of deuteron (), triton (), helium-3 (He), and hypertriton (H) measured in Au-Au collisions from the RHIC Beam Energy Scan I and II, and also provide the corresponding predictions of different hypernuclei , , and . We further study the production correlations of different species of light (hyper-)nuclei and discuss their interesting behaviors as a function of collision energy.
