主　　题：nucleon coalescence light nuclei heavy-ion collision 

摘      要：The nucleon coalescence model is one of the most popular theoretical models for light nuclei production in high-energy heavy-ion *** production of light nuclei d,t,^(3)He,and^(4)He is studied using the transport model JAM with a simplified afterburner coalescence at√^(s)NN=3 GeV Au+Au *** scan the cut-off of phenomenological coalescence parameters,i.e.,the relative spatial distance△R and momentum difference△P,for the formation of light nuclei by nucleon coalescence to reproduce the light nuclei pTspectra measured by the STAR *** results indicate a potential connection between the coalescence parameters and the binding energy as well as the diameter of these light nuclei.
