摘要：
The nucleon coalescence model is one of the most popular theoretical models for light nuclei production in high-energy heavy-ion collisions.The production of light nuclei d,t,3He,and4He is studied using the transport model JAM with a simplified afterburner coalescence at■GeV Au+Au collisions.We 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 experiment.The results indicate a potential connection between the coalescence parameters and the binding energy as well as the diameter of these light nuclei.
