Abstract：
The construction of BEPCⅡ/BESⅢ is under plan. Both the accelerator and detector will have much better performance than BEPCⅠ/BESⅡ. Under certain assumptions on ¹P₁ and η′_c decay modes and branching ratios and on the BESⅢ detector performance,and assuming 3×10⁹ ψ(2S) events data sample,the simulation shows that clear signals of ¹P₁ and η′_c can be identified with rather low background.
