Abstract：
In the framework of the potential model for charmonium,the effects of 2 ³S ₁-1 ³D ₁mixing between ψ(3770) and ψ(3686) are discussed.It is concluded that the possibility for the mixing angle θ=30° should be ruled out.While the results for both ψ(3770)→γχ ₀and ψ(3686)→γχ ₀are improved with θ=－10°,the contradiction between the theoretical value and the experimental value for ψ(3770)→γχ ₁still remains.
