Abstract：
In the angular distribution measurement of ψ′→pp, the sample of J/ψ→pp selected from 58M J/ψ events with high statistics is used to determine the polar angle dependent efficiency, and to correct the Monte Carlo efficiency in ψ′→pp. The systematic error of this method is also analyzed. The obtained efficiencies and related errors are used for the measurement of angular distribution of ψ′→pp.
