Abstract：
In the framework of the potential model, the mass, width and branching ratios of η' _care estimated. It is shown that it is possible for the width of the forbidden Ml transition η' _c→ γJ/ ψto raise one order of magnitude after considering relativistic corrections in comparison with the non-relativistic result. The possibilities to measure the cascade electromagnetic radiation processes ψ'/(3686) → γ η' _c→ γ γ ¹ P ₁, γ γJ/ ψ,3 γat the Beijing Electron-Positron Collider (BEPC) are discussed.
