Abstract：
A hadron and string cascade model, JPCIAE, which is based on LUND string model, PYTHIA event generator especially, is used to study the photon production of 200 A GeV S + An central collisions. The model takes into account photon produced from the partonic QCD scattering processe, the final-state hadronic interaction, and hadronic decay and deals with them consistently. The results of JPCIAE model reproduce successfully the WA93 data of low P_T enhancement. We have compared the contributions from different decay channels and discussed the role played by rescattering.
