Abstract：
By using experimental data obtained from the measurement of β-delayed proton decay of ⁶⁵Se produced in the ⁴⁰Ga(²⁸Si,3n) reaction, the absolute detection efficiency of particle telescope for rotating radioactive source was fitted and calculated. The half-life of ⁶⁵Se was thus accurately determined to be 9.6_-4.1^+5.3 ms and its β-delayed proton energy of ⁶⁵Se was 3.70±0.08MeV. The partial decay scheme of ⁶⁵Se β-delayed proton decay was revised.
