Abstract：
Using Monte Carlo simulation,the process of J/ψ→γX→γηη′(η′→γρ0,ρ0→π+π-,η→γγ)is studied on BEPCⅡ/BESⅢ. Based on the better performance of BESⅢ and the large J/ψ data sample,it's possible to search for glueball state candidates and confirm their existence. Based on the study of this J/ψ radiative decay channel,it provides us some useful data for the selection of crystal BGO or CsI of electromagnetic calorimeter and for the selection of magnetic field intensity.
